Ā Night vision isĀ the ability to see in low-light conditions, either naturally withĀ scotopic visionĀ or through a night-vision device. Night vision requires both sufficient spectral range and sufficient intensity range.
Night vision devices let you see in the dark. With quality night vision goggles and scopes you can see people, animals, and objects up to 1,000 yards away on a dark night. Night vision monocular cameras let you take photographs and videos of things you can't see in the dark with your naked eyes.
There are actually two similar technologies used in night vision equipment. Traditional night vision devices useĀ optoelectronic image enhancement, which works by sensing small amounts of infrared light that are reflected off objects and then electrically amplifying that light into a characteristic glowing green image. A newer technology,Ā digital image enhancement, captures available light on a digital image sensor and then digitally enhances the images in a full-color display.
