Humans have always preferred to live their lives by daylight. I used to think it was because human beings have crappy night vision, and it wasn’t until I got older and more cynical that I realized it was because they have less to be afraid of during the day.
Introductory headline
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 use 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, digital image enhancement, captures available light on a digital image sensor and then digitally enhances the images in a full-color display.
Applications
Night vision technology is used in several types of devices, all designed to enhance viewing in dark or low-light environments.
Perhaps the most popular consumer user of night vision technology can be found in scopes. A scope is a telescopic sighting device used to view distant objects. Scopes can be either freestanding (handheld) or mounted onto certain types of firearms, such as rifles. Night vision scopes can be monocular (a single eyepiece) or binocular (two eyepieces for a stereoscopic image).
Night vision goggles are also popular. Think of these goggles as a binocular scope incorporated onto a head strap or helmet. Because goggles are worn instead of held, they free up your hands for other purposes. They’re great for when you’re moving around at night or in dark buildings.
Finally, many still and video cameras incorporate digital night vision technology for shooting at night. Night vision cameras are often used for surveillance purposes, especially around a building’s unlit perimeter.
