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 ...
OOB light is not visible to most commercial devices. Despite ITAR restrictions, night vision proliferated among peer and near-peer countries and into terrorist hands such as the Taliban Red Unit. [47] Friendly forces using night vision equipment such as IR illuminators, IR strobes, or IR lasers, can be spotted. OOB tech are much more difficult ...
However, night vision concerns the ability to see in the dark although not necessarily in the infrared spectrum. In fact, night vision equipment can be manufactured using one of two technologies: [4] light intensifiers or infrared vision. The former technology uses a photocathode to convert light (in the visible or near infrared portions of the ...
Infrared is used in night vision equipment when there is insufficient visible light to see. [33] Night vision devices operate through a process involving the conversion of ambient light photons into electrons that are then amplified by a chemical and electrical process and then converted back into visible light.

1x. The AN/PSQ-20 Enhanced Night Vision Goggle (ENVG) is a third-generation passive monocular night vision device developed for the United States Armed Forces by ITT Exelis. It fuses image-intensifying and thermal-imaging technologies, enabling vision in conditions with very little light. The two methods can be used simultaneously or individually.
Automotive night vision. An automotive night vision system uses a thermographic camera to increase a driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights. Such systems are offered as optional equipment on certain premium vehicles.
