The terms Hor+, static (previously anamorphic), pixel-based, Vert- and stretch are widely used in gaming discussions to describe how different video games change field of view dependent on the aspect ratio of the rendering resolution. The terms were originally coined by members of the Widescreen Gaming Forum.[6]

The frequency can even be tripled or even quadrupled to give a wavelength of 355 nm and 266 nm. These would be invisible.

The different values for horizontal and vertical FOV may lead to confusion because the games often just mention FOV and not whether they mean the horizontal or vertical FOV.

The active medium is a dye solution. Below is an example of a dye laser used at a university. We have the laser unit resting on the table and the dye is continuously circulated through pipes. This specific laser is a tuneable laser capable of emitting wavelengths between 530nm and 590 nm. (nm – nanometres)

The FOV in a video game may change depending on the aspect ratio of the rendering resolution. In computer games and modern game consoles the FOV normally increases with a wider aspect ratio of the rendering resolution.[1]

In first person video games, the field of view or field of vision (abbreviated FOV) is the extent of the observable game world that is seen on the display at any given moment. It is typically measured as an angle, although whether this angle is the horizontal, vertical, or diagonal component of the field of view varies from game to game.

This picture has been shown for reference and should not be copied, there are a number of bad habits here. We have a class 4 laser with open beam paths. The dye has obviously been leaking as we can see by the residue on the side of the table and, underneath, is the high voltage power supply potentially catching the drips. This has been shown to highlight the dangers that need to be considered.

Temporary changes to the field of view can sometimes be used as a special effect in video games. Reducing the field of view is commonly used to convey focus, whereas widening it may increase perceived movement speed or indicate lack of control.

Including peripheral vision, the visual field of the average person is approximately 170–180 degrees. Console games are usually played on a TV at a large distance from the viewer, while PC games are usually played on computer monitors close to the viewer. Therefore, a narrow FOV of around 60 degrees is used for console games as the screen subtends a small part of the viewer's visual field, and a larger FOV of 90 to 100 degrees is usually set for PC games as the screen occupies a larger amount of the viewer's vision.

The active medium of a laser is the part that is excited by an external energy source. Gas lasers have an active medium that is a gas. They can be filled with different gases whether this is argon, helium or carbon dioxide. (CO2.)

The field of view is usually given as an angle for the horizontal or vertical component of the FOV. A larger angle indicates a larger field of view. However, depending on the FOV scaling method used by the game, it may only affect the horizontal or the vertical component of the field of view.

Semiconductors like the ones found in laser pointers are typically small hand held lasers that are battery operated. The main problem is that the output powers of these lasers have been steadily increasing leading to potentially dangerous situations in the wrong hands.

Narrowing the field of view can be a technique used to improve performance, as it can allow you to have to render less objects through the common optimisation technique of viewing-frustum culling.

Many PC games that are released after 2000 are ported from consoles, or developed for both console and PC platforms. Ideally, the developer will set a wider FOV in the PC release, or offer a setting to change the FOV to the player's preference. However, in many cases the narrow FOV of the console release is retained in the PC version. This results in an uncomfortable sensation likened to viewing the scene through binoculars, and may lead to disorientation, dizziness, or nausea.[3][4][5]

H = 2 arctan ⁡ ( tan ⁡ ( V 2 ) × w h ) {\displaystyle H=2\arctan \left(\tan \left({V \over 2}\right)\times {w \over h}\right)}

The active medium is a solid, transparent material. The cavity is filled with a crystalline material traditionally based around a gemstone such as a ruby, sapphire or emerald. But these days they are composed of man made materials such as the Nd:YAG (neodymium-doped, yttrium aluminium garnet). These lasers emit light with a wavelength of 1064 nm, which is the near infrared. But with the use of clever optics the frequency can be doubled (this will halve the wavelength to 532 nm). This now produces a green laser emission as seen in hand held laser pointers.
