Abstract
The image intensifier based night vision goggle which has proven so useful in low light or night observation applications, can be mated to the typical CD video camera for imaging under these adverse lighting conditions. Image intensifiers have specific spectral response, low light sensitivity, resolution, and electronic characteristics to augment standard CCD camera capability and thus provide video suited for reconnaissance. The variety of these devices include the Gen I, Gen II and the Gen II series of image intensifiers. Recent developments have increased the variety of spectral response, quantum efficiencies and spatial resolution within the Gen II and Gen III types. The SPIE Airborne Reconnaissance session paper presented in 1995 entitled 'Advanced in Low Light Level Video Imaging' described the then available image intensifiers. This paper explores and updates the data of the 1995 paper and discusses the changes and improvements in image intensifiers since the original paper. Additional information concerning the CCD camera and image intensification for reconnaissance applications is also presented.
