Energy resolution of dual-channel opto-electronic surveillance system

摘要

Dual-channel opto-electronic surveillance systems which operate in visible and infrared spectrum ranges are widespread. Their analysis and design needs suitable tools. A simplified physics-mathematical model of a dual-channel optoelectronic surveillance system was developed to determine energy resolution of the system. Noise equivalent brightness difference and noise equivalent temperature difference were used to define the ability of television and thermal imaging systems to detect objects. As an example of applying the model an algorithm of spectral channel selection depending on the conditions of surveillance was developed.
