The sensitivity of a (digital or film) imaging system is typically described in the terms of the signal level that yields a threshold level of SNR. Industry standards define sensitivity in terms of the ISO film speed equivalent, using SNR thresholds (at average scene luminance) of 40:1 for "excellent" image quality and 10:1 for "acceptable ...
The effect on the natural night vision of the eye is evident A standard telescopic sight augmented with a night-vision device in front on the M110. Note that in addition to the image intensifier, the NVD gathers much more light by its much larger aperture A 1PN51-2 night-vision reticle with markings for range estimation First-person view ...
Digital night vision relies on high sensitivity back-illuminated CMOS image sensors, also sometimes called sCMOS (scientific CMOS). Their sensitivity can exceed the sensitivity of the human eye. [13] These sensors can be head-mounted in night vision goggles and rifle scopes, but are also used in security camera systems, astronomy, and ...
AN/PAS-13 Ver. 2 mounted on an AR-15 with a brass catcher. In November 2006, three new versions of the AN/PAS-13 were ordered by the U.S. military. The Thermal Weapon Sights II include three new versions, a Light, Medium, and Heavy. All three models weigh less than the originals, weighing 1.8 lbs, 2.8 lbs, and 3.9 lbs respectively.
Color blindness changes the sensitivity of the eye as a function of wavelength. For people with protanopia , the peak of the eye's response is shifted toward the short-wave part of the spectrum (approximately 540 nm), while for people with deuteranopia , there is a slight shift in the peak of the spectrum, to about 560 nm.

It is known that the rod cells are more suited to scotopic vision and cone cells to photopic vision, and that they differ in their sensitivity to different wavelengths of light. [ 2 ] [ 3 ] It has been established that the maximum spectral sensitivity of the human eye under daylight conditions is at a wavelength of 555 nm , while at night the ...
