Visual systems for employment at low light levels are examined from two points of view As extensions of the human visual system and As optical information acquisition and conversion systems. The first point of view is adopted to examine the general suitability and the limitations of reliance on the dark-adapted human eye alone, the dark-adapted human eye aided by binoculars, and the light-adapted human eye aided by photoelectronic imaging systems such as image intensifiers and low-light-level television. The second point of view is adopted to analyze the dependence of photoelectronic imaging system performance on system parameters.
