The Passive night vision devices such as digital NVD make use of the other ambient light as the source for the intensification process instead of using this infrared lighting source. The infrared night vision device requires the infrared light source for image amplification, which can be easily identified and destroyed by the enemies and natural outsources. But the
But, the non-infrared night vision devices make use of the surrounding ambient light source for amplifying the image vision. It makes use of the CCD and CMOS sensor technology to capture the better imaging light on the targeted objects.
