2. Night vision - Wikipedia

   en.wikipedia.org/wiki/Night_vision

   Night vision is the ability to see in low-light conditions, either naturally with scotopic vision or through a night-vision device. Night vision requires both sufficient spectral range and sufficient intensity range. Humans have poor night vision compared to many animals such as cats, dogs, foxes and rabbits, in part because the human eye lacks ...

3. AN/PSQ-42 - Wikipedia

   en.wikipedia.org/wiki/AN/PSQ-42

   Helmet mounted 4x AA-type battery pack. The AN/PSQ-42 Enhanced Night Vision Goggle-Binocular (ENVG-B) is a third-generation passive binocular night vision device developed for the United States Army by L3Harris. It combines dual tube image-intensifying (I²) and thermal-imaging technologies into a single goggle, enabling vision in low-light ...

4. Night-vision device - Wikipedia

   en.wikipedia.org/wiki/Night-vision_device

   A night vision device usually consists of an image intensifier tube, a protective housing, and an optional mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front/ objective lens to prevent damage by environmental hazards, [ 1 ] while some incorporate telescopic lenses.

   AN/PVS-4. AN/PVS-4 (Night Vision Sight, Individual Served Weapon, AN/PVS-4) is the U.S. military designation for a specification of the first second generation passive Night vision device. The AN/PVS-4 first saw widespread use during the Gulf War and later some deployment in the Iraq War and has since been replaced by modern third-generation ...

8. Infrared vision - Wikipedia

   en.wikipedia.org/wiki/Infrared_vision

   Infrared vision is the capability of biological or artificial systems to detect infrared radiation. The terms thermal vision and thermal imaging [1][2] are also commonly used in this context since infrared emissions from a body are directly related to their temperature: hotter objects emit more energy in the infrared spectrum than colder ones.

9. Automotive night vision - Wikipedia

   en.wikipedia.org/wiki/Automotive_night_vision

   DS Night Vision offers road visibility by night. An infrared camera in the front grill identifies objects, pedestrians and animals on the road at a distance of up to 100m. [citation needed] A digital instrument cluster shows the driver the area around the car in infrared, with a yellow line around any sources of potential danger.
