Abstract
Electro-optical sensors can be of significant aid to our law enforcement agencies particularly if their capabilities and limitations are fully understood. In the following, the imaging process is discussed as it applies to the needs and requirements of security, surveillance and law enforcement. Our approach is to associate quantitative signal-to-noise ratios with simple geometric images as developed by electro-optical sensors, to determine the observer's SNR needs through psychophysical experimentation and then, through further psychophysical experimentation, to correlate the detectability of these simple images with the visual discrimination of the images of real objects. The visual discrimination tasks we consider are simple image detection and the higher order tasks of recognition and identification. The concepts developed form a rational basis for the selection of electro-optical equipments which have a reasonable expectation of actually performing a desired function.
