    The impact of lighting on night vision goggles

    As we all know night vision goggles need a light source in order to work, since they are in theircore light intensifiers. The main purpose of night vision is to senseradiation that is invisible to the human eye. The human vision is limited to a verysmall portion of the electromagnetic spectrum called visiblelight. What the night vision dose is enhance the spectral range by usingsources of the spectrum that are otherwise not visible. These include nearinfra-red or ultra violet radiation.

    Currently we have two types of night vision, imageintensification and CMOS technology.

    Image intensifiers or enhancers actually magnify the amount orphotons received from various sources in nature, such as moon or starlight. Thereason why the image is intensified is the fact that the output visible lightis brighter than the incoming light. The image-enhancement systems are alsocalled night-vision devices or NVDs and they rely on a special tube –image-intensifier tube, to collect and amplify infrared and visible light. but The displayingimage for regular light intensified technology is green image, not clearenough for observation. While intensify tube will be burnt out or shutdown forminutes which may lose the best battle chance.

    Our smallest night visiongoggle with CMOS system has aspherical objective lens + sensor (made in Korea)+ photoelectric conversion version, video processor, image display panel + OLEDdisplay, CMOS higher sensitivity, shorter exposure times and shrinking pixelsize. In the daytime,the heat reads exactly as it does in the dark. The collected thermalinformation can not be "exposed" and the highlight of the capacity isstill of great value in daylight. A goal in camouflage or far will transmit theheat that the device will send, regardless of the sun's brightness.
