Paper Abstract

The performance of image intensifiers is rated according to their capability of detecting, recognizing, and identifying objects at low light levels. The most important parameters limiting these capabilities are noise and imaging parameters. Noise parameters are normally expressed in signal to noise ratios, noise power spectra and noise statistics, whereas imaging parameters are described by the modulation transfer function and veiling glare. This paper will describe the instrumentation and methods used at the Night Vision Laboratory to determine these parameters. In developing the instrumentation and test methods, special consideration has been given to a clear separation of noise and imaging parameters.
