Glenn Greenwald said that American media elites love to mock Russian media, especially RT, as being a source of shameless pro-Putin propaganda, where free expression is strictly barred. Agreeing the "network has a strong pro-Russian bias", he suggested that Martin's action "remarkably demonstrated what 'journalistic independence' means".[33]

After losing the majority of its cable and satellite coverage, the channel ceased operations of all live programming on March 3, 2022, with T&R Productions indicating the layoffs of all off- and on-air staff would be permanent.[7]

Incidents centered upon RT America include Breaking the Set host Abby Martin's 2014 statement of her opposition to Russia's intervention in Ukraine,[8] which was followed the next day by anchor Liz Wahl's on-the-air resignation, which she issued on account of her belief that RT was a propaganda machine for President Vladimir Putin.[9] In 2017, David Z. Morris wrote in Fortune that, "according to a[n unnamed] social network analyst interviewed by The [New York] Times, RT is not simply a platform for a right-wing agenda. Rather, it fuels fringe viewpoints across the political spectrum, providing grist for libertarian, far-left, and anti-globalization factions as well."[10] James Kirchick wrote in The Washington Post that the channel was "not a 'news service' in any meaningful sense of the term".[11]

The irradiation solid angle is the angle of incident light to a point on an object, and the size of the irradiation solid angle controls the appearance of unevenness.

In response, RT released a statement: "When a journalist disagrees with the editorial position of his or her organization, the usual course of action is to address those grievances with the editor, and, if they cannot be resolved, to quit like a professional. But when someone makes a big public show of a personal decision, it is nothing more than a self-promotional stunt. We wish Liz the best of luck on her chosen path".[36]

Exposure of certain objects, including phosphors, to ultraviolet light causes a fluorescence phenomenon (excitation) that absorbs the ultraviolet light and emits light with a longer wavelength.This allows the position of objects that are difficult to recognize with visible light to be captured more easily.

The network was removed from the services offered by DirecTV on March 1, 2022, following Russia's invasion of Ukraine, with Ora Media pausing production on several shows it produced for RT America.[18] Dish Network dropped the channel on March 4.[19]

In October 2017, after the United States Department of Justice insisted that RT America register as a "foreign agent" under the Foreign Agents Registration Act (FARA), the Russian Justice Ministry declared "foreign agents" several U.S.-government funded media outlets, including the Voice of America and Radio Free Europe/Radio Liberty.[14][15] RT America's editor in chief, Margarita Simonyan, said that it would comply with the demand in order to avoid further legal action by the U.S. government,[16] but blasted the move noting that registration also resulted in the TV channel losing its Congressional press credentials,[17] and undermined assertions by the U.S. Department of Justice that FARA registration would not have any effect on the channel's ability to operate in the United States.[15]

On March 4, 2014, Breaking the Set host Abby Martin (whose show was at the time produced by RT America), speaking directly to her viewing audience during the show's closing statement, said that although she worked for RT, she was against Russia's intervention in Ukraine. She said that "what Russia did is wrong", as she is against intervention by any nation into another country's affairs.[8] Later, Martin asserted that RT still supported her despite her differences of opinion with the Russian government.[31] RT's press office suggested that Martin would be sent to Crimea, and responded to accusations of propaganda, stating "the charges of propaganda tend to pop up every time a news outlet, particularly RT, dares to show the side of events that does not fit the mainstream narrative, regardless of the realities on the ground. This happened in Georgia, this is happening in Ukraine".[32][note 1]

“Light” is a class of waves called electromagnetic waves.The range of this light that the human eye can perceive is called “visible light” and extends from about 380 nm to 780 nm (nanometers).The wavelength range used in imaging is even wider than visible light, ranging from ultraviolet to infrared.

A rough, low-reflective workpiece such as paper or untreated wood will appear equally bright no matter where the light is projected.On the other hand, a workpiece that is shiny and highly reflective, such as a mirror, polished metal or glass, is captured in a completely different image depending on where the light is projected from.

RT America was a U.S.-based news channel headquartered in Washington, D.C. Owned by TV Novosti and operated by production company T&R Productions,[1] it was a part of the RT network, a global multilingual television news network based in Moscow and funded by the Russian government.[2][3][4] The channel said it reached an audience of 85 million people in the United States, but this figure is disputed.[5] It was distributed through select cable providers, over-the-top services, a live stream through its website, and three low-power digital subchannels.[6] Since the channel's closure, viewers who tune into the cable channel or their live stream are being shown a live feed of an RT International broadcast instead.[7]

They get these extreme voices on that have this kind of hostile toward the West viewpoints towards the world, very extremist. These are the people that they have on. And when I was on the anchor desk, they would instruct you to egg on these guests and try to get them, you know, rallied up, to really fire off their anti-American talking points. Listen, I'm all about exposing government corruption. I'm all about being critical of the government. But this is different. This is promoting the foreign policy of somebody that has just invaded a country, has invaded the country and is then lying about it, is using the media as a tool to fulfill his foreign policy interests. And RT is part of Putin's propaganda network and it's very, very troubling in the wake of what is going on in Ukraine today.[37]

Using this property, we can control whether an object is “brightened” or “darkened” by using monochromatic lighting on a colored object.“In fact, using a monochrome camera and lighting a red (R) green (G) and blue (B) object with each color of red (R), green (G), and blue (B) will produce the following image.

James Kirchick wrote in The Washington Post in September 2017 that "RT is not a 'news service' in any meaningful sense of the term. Reputable news services don't employ Illuminati correspondents. RT has no regard whatsoever for basic journalistic values like objectivity or the pursuit of truth."[11] Kirchick was a guest in August 2013 to talk about Chelsea Manning, and used the opportunity to "speak out against the horrific anti-gay legislation" which had recently been approved by President Putin. The clip went viral on social media.[24]

Among the channel's shows at its closure were Dennis Miller + One with Dennis Miller, CrossTalk with Peter Lavelle and The Keiser Report with Max Keiser. Other shows included News with Ed Schultz (2016–2018) and Larry King Now (2012–2020). Additional personalities included Rick Sanchez, Stacy Herbert, Chris Hedges, Jesse Ventura, Sean Stone, Lee Camp, Mike Papantonio and Ben Swann.

On January 12, 2017, during a live House of Representatives debate on the Securities and Exchange Commission, C-SPAN 1's live broadcast was suddenly interrupted by a cut-in of RT America. C-SPAN explained the interruption as a technical malfunction, blaming it on an internal routing error, that moved the RT America feed from an internal monitor within C-SPAN used to monitor the network alongside others to the broadcast feed for C-SPAN 1.[38]

After losing the majority of its cable and satellite coverage following the Russian invasion of Ukraine, the channel ceased operations of all live programming on March 3, 2022, with T&R Productions indicating the layoffs of all off- and on-air staff would be permanent.[12]

According to David Z. Morris, writing in Fortune magazine in 2017, "in its early years, RT provided a platform for various fringe or simply false narratives in American public discourse," with guests on the network "arguing that the 9/11 attacks were a CIA conspiracy and that Osama bin Laden's death was faked."[10] According to him, "RT America has been more likely to highlight legitimate but marginalized political perspectives, and further blurs the line between propaganda and commentary by employing respected U.S. journalists such as Chris Hedges, Ed Schultz, and Larry King."[10] He also added that during the 2016 U.S. presidential election campaign, RT published conspiracy theories about the murder of Seth Rich to undermine the Hillary Clinton campaign. Some of these gained traction on social media and were distributed around the internet.[10]

Wahl said that what "broke" her was that RT censored a question from her interview with Ron Paul about "Russia's intervention in Ukraine".[citation needed]

The color of an object is determined by the color of the light that reaches the object from a light source, such as the sun, and is reflected without being absorbed by the object.

(1) When you want to make the unevenness stand out as a defect.(2) When you do not want the unevenness to stand for defects, but want to detect other stains, etc.

If you want to image a small workpiece at high resolution, it is necessary to carefully select the wavelength of the lighting and the numerical aperture of the lens.

I cannot be part of a network funded by the Russian government that whitewashes the actions of Putin. I am proud to be an American and believe in disseminating the truth. And that is why, after this newscast, I am resigning.[9]

RT stated that while it was testing its systems in preparation for the inauguration of Donald Trump, its signal was "mistakenly routed onto the primary encoder feeding C-SPAN 1's signal to the internet, rather than to an unused backup."[39]

The channel was launched in the United States in February 2010[citation needed] as RT was looking to increase its reach. It was launched along with Rusiya Al-Yaum in 2007, the Spanish-language channel RT Actualidad in 2009, and the RT Documentary channel in 2011.[13]

(Example 3)When detecting blue stains on a red object, red lighting can be used to capture the object brighter and the stain darker, resulting in a high-contrast image.

The three most basic colors are Red, Green, and Blue and are represented by the acronym RGB.Mixing the three colors of light in equal proportions produces white light.Indoor lighting such as fluorescent lamps and sunlight appear white because the various colors of light are mixed in proportion to each other.In addition, almost any color can be produced by controlling the balance of RGB.

William Broad of The New York Times wrote about the network's coverage of 5G, the mobile phone technology. Broad said the network aired seven programs in 2019 on the subject up to mid-April that year. One of these, entitled A Dangerous 'Experiment on Humanity', Broad commented, linked 5G "signals to brain cancer, infertility, autism, heart tumors and Alzheimer's disease — claims that lack scientific support".[25] According to Broad, the channel focused on Vaxxed: From Cover-Up to Catastrophe, a 2016 film by the British anti-vaccine campaigner Andrew Wakefield, to echo the charge by an unnamed black minister in Los Angeles who was seen in a video addressing an audience and, according to Broad, saying that "childhood immunizations had caused autism in 200,000 black children."[26] Domestically, in Russia itself, President Putin is a firm advocate of vaccinations.[27]

It can transmit through specific objects. This allows detection of substances within the object that are not visible with visible light.It can also darken and detect areas that contain more moisture than their surroundings, due to the absorption properties of moisture in a specific wavelength range of infrared light.

The lighting is uneven on both sides and top and bottom, and the lighting is partly reflected in the image making it too bright.

Resolution is expressed by the above formula, but if the same lens (same NA) is used, the longer the wavelength, the greater the spatial resolution=less finely resolved.

AS manufacturing technology has advanced in recent years, various products can be mass-produced in a short period of time. As a result, “product inspections” are no longer able to keep up with visual inspections by humans due to the demand for higher accuracy, inspection speed, and difficulty in training new employees. Replacement of visual inspection is underway with machine vision (image processing equipment), which inspects products for defects based on image data captured by industrial cameras and lenses.Machine vision has many advantages, such as 24-hour operation, programmable operation, and reduced variation in inspection results. However, machine vision is not simply a matter of installing cameras. In fact, the human eye excels in its ability to constantly focus on a product depending on its distance and viewing angle, and it is able to recognize both bright and dark areas in a single glance. It can flexibly respond to any given situation. In contrast, machine vision often requires a single image of the product being delivered by a fixed camera, lens, and lighting, and unless the defective part is clearly visible in the image, it is impossible to correctly determine whether the product passed or failed.

In a March 2014 Politico article, Wahl expanded on her resignation statement, saying, "For about two and a half years. I'd looked the other way as the network smeared America for the sake of making the Kremlin look better by comparison, while it sugarcoated atrocities by one brutal dictator after another."[9]

In addition to highlighting defects, the same concept of lighting selection can be used to eliminate excess background or unnecessary objects.

(Example 1)If white light is shined on a red apple, it will appear red because it absorbs blue and green light and reflects only red.f green light is shined on a red apple, it absorbs green and reflects no color, making it appear black.

A 2017 report by the United States Intelligence Community characterized RT as "the Kremlin's principal international propaganda outlet" and said that RT America had been set up as an autonomous nonprofit organization to avoid the Foreign Agent Registration Act's registration requirement.[21][22]

Adjust the brightness of the lighting and the shutter speed of the camera to clearly define the areas you want to emphasize and those you prefer not to.

It is necessary to obtain completely different results for (1) and (2), which can be achieved by adjusting the “irradiation solid angle”

An Oxford University study interviewing 23 of RT's journalists noted that it regularly hired personalities with little or no experience, often making employment offers before they graduated from college, so that it could influence their work more easily. One of its leading personalities, Rachel Blevins, was recruited from her work on fringe websites and radio networks; she accepted the RT offer largely because it was in line with her left-wing and "anti-imperialist" philosophies far more than other American networks, and she continued to defend the network until (and after) its demise.[28]

In their investigation of alleged Russian meddling in the U.S. 2016 elections, the U.S. intelligence services stated that they had "high confidence" that RT was involved in a campaign ordered by President Vladimir Putin. The New York Times reported their findings in 2017 indicating that "the attack was carried out through the targeted use of real information, some open and some hacked, and the creation of false reports, or 'fake news,' broadcast on state-funded news media like RT and its sibling."[23]

When asked by Brian Stelter, host of CNN's Reliable Sources, about a clip of her interviewing a guest on RT, Wahl responded,

(Example 2)When white light is shined on a yellow banana, it absorbs blue light and retlects a mixture of red and green light, making it appear yellowish.“If you shine blue light on a yellow banana, it absorbs blue and appears blackish because it absorbs blue.

The day after Martin's statement, RT America anchor Liz Wahl resigned on air, which she said was due to her belief that RT was a propaganda machine for President Vladimir Putin.[34] She stated:[35][9]

Among wavelengths invisible to the human eye, wavelengths shorter than visible light are called “ultraviolet light” and longer wavelengths are called “infrared light”.(See the figure on the previous page.)

The basic idea is to focus on the object by adjusting the depth of field with the aperture and brightness of the lighting.(In some cases, the image may be intentionally blurred.)

As shown above, when the light source color that includes the color of the object is irradiated, the object can be imaged brightly (white).Conversely, if the object is illuminated by a light source color that does not include the object’s color, the object can be imaged dark (black).

As described above, the color, type, size, and installation method of lighting can change the way an object is seen. The selection of the lighting is essential together with the camera and lens.VS Technology offers verification with actual objects, so please contact us for more information.

There is no difference under natural and visible light, but as we move to longer wavelengths, the water appears blacker and the difference becomes clearer.
