    Turning Night Into Day – CMOS Night Vision Goggles

    • Author:Durham Technology
    • Release on :2018-12-26
    The human eye needs a certain amount of available light to see anything at all. Some animals, like cats and owls, can see much better in darkness because their pupils are large enough to take in more available light than the human eye can. Night vision goggles (NVG), is anoptoelectronic device that allows images to be produced in levels of light approaching total darkness. Night vision devices were first used in World War II and came into wide use during the Vietnam War The technology has evolved greatly since their introduction, leading to several "generations" of night vision equipment with performance increasing and price decreasing. Consequently, they are available for a wide range of applications, e.g. for gunners, outdoor enthusiast, drivers and aviators.


    How Does CMOS Night Vision Work?


    Night vision is the ability to see in low-light conditions. CMOS night vision gathered available light by the front aspherical objective Lens, where it is transmitted through a set of optical lenses to the CMOS chip.  High levels of energy, produced by the device's complex power supply, knock out electrons from the Photocathode Screen, located on the front of the Electronic Intensifier Tube. This same energy creates a highly static field, pushing the electrons to the Phosphorescent Screen, a sensitive layer, located on the back of the CMOS. These electrons strike the Phosphorescent Screen with great speed, causing the screen to illuminate. This process produces an image, which is then magnified by the Lens located at the back of the device. By looking through the lens you will see the image as if you just looked through a regular optical device, except the image will appear in a black white color. Finally, the Lens provides adjustment for your particular eyesight, while the Objective Lens lets you adjust the focus according to the distance of the object you are viewing.


    What Are Some Uses for CMOS Night Vision?    


    Search and Rescue Teams use night vision to locate lost people in low-light situations.


    In Natural Disaster situations, public safety personnel use night vision devices to help them see when power goes out for extended periods.


    Night vision is a helpful tool for students of wildlife behavior, so they can remain undetected while observing nocturnal species.


    Night Hunting or Fishing Night vision devices can help you see your surroundings, and find animals. Some hunting and fishing gear is equipped with night vision devices specifically for nighttime use.    


    Night War Night vision goggles allow war fighters to see the enemy at night, or in the darkness of a cave, for example, as clearly as they do during the day.
