Image: Visible thunderstorm cloud base near Lebanon, Indiana on 15 June 2016. Researchers at Purdue University’s Earth, Atmospheric, and Planetary Sciences Department conducted a test program to determine the practicality of using Shortwave Infrared (SWIR) imaging to improve detection of poorly-visible tornadoes in supercell thunderstorms. The research concluded that there is a distinct possibility that SWIR video imagery can be beneficial to storm spotters. In particular it found that, “an ambiguous, non-tornadic cloud base lowering was quickly dismissed by a participant viewing the scene in SWIR, while a participant viewing the same scene in VIS light had a more difficult time determining that the feature was non-tornadic. Because SWIR light is less susceptible to scattering by intervening haze, allowing cloud base features to be more easily discerned.”

Longer wavelengths of light pass more easily through atmospheric obscurants such as dust, haze, and smoke. Because the SWIR band has a longer wavelength than visible, Sensors Unlimited SWIR cameras are able to image scenes behind light smoke as seen in the forest fire image above.

Jun 19, 2024 — The Power Profiler Kit II (PPK2) is an affordable, flexible tool that measures the real-time power consumption of your designs.

Maintenance and repair work is costly to residential and commercial building owners. Each interior and exterior wall can contain valuable information below the paint surface.

SWIR direct image close-ups of the human eye, as shown above, demonstrates the level of detail captured. The transparency of the cornea extends well into the SWIR band and combined with reduced tissue scattering improves the fine detail captured over that of visible based cameras. This fine structure is a unique identifier of the individual so biometric matching algorithms and databases acquired in the visible should be fully applicable to the SWIR images. This opens up new flexibility in capturing iris images. Most importantly, SWIR offers the ability to capture iris images at distance with controlled lighting sources that are eyesafe and essentially undetectable as they don’t even trigger closure of the iris. SWIR offers the unique capability to capture iris images even when the individual wears regular eye glasses or even sunglasses.

SWIR cameras can detect hot temperatures similar to those observed in hot glass inspection. Using a SWIR camera, the hot wine glass is false colored to show the evenness of the heated areas of the glass. Additionally, SWIR light passes through glass, as demonstrated by the business card behind the wine glass. Sensors Unlimited SWIR cameras can be used for industrial inspection of glass manufacturing to detect defects and reduce scrap.

The image above was taken 2 hours after sunset on a full moon night at a range of 250 m. The SWIR image above was taken using the high definition 1280x1024 JSX camera. The image was captured using a 50 mm f/1.4 SWIR optimized lens with exposure set to 1/30 sec. Due to ambient irradiance of the night sky, Sensors Unlimited’s high gain SWIR cameras are able to produce clear nighttime imagery over visible imagery.

SWIR image of the same scene using a Sensors Unlimited SWIR camera. SWIR light interacts with objects similar to visible light, therefore producing a familiar image through the glass window. Notice the cars in the parking lot have shadows similar to those produced by visible cameras. Because SWIR light passes through glass, commercial visible lenses can be used to produce SWIR imagery. However, imagery can be enhanced greater using a SWIR optimized lens.

The SWIR image easily defeats the disguise worn by the actor. Human hair and natural fabrics such as cotton are highly reflective in SWIR. Notice in the SWIR image where the actor’s natural hair meets the artificial facial hair worn in the disguise. Further note the actor’s black suit and shirt appear white in SWIR.
