Proposals to set up the new performance model for thermal imaging systems

摘要

The important function and signification of researching on performance model for photo electronic systems is discussed, and the emphasis is on the thermal imaging system models for their technical characteristics and developing history. Based on analyzing and studying existing detection theory and performance models of thermal imaging systems limitations and deficiencies are pointed out. The proposals for establishing the new threshold detection theory, apparent distance detecting equation and performance model are put forward in this paper, which will be based on the quantum noise fluctuation theory and linear filter theory, the threshold characteristics and visual theories of the human eye, and can been widely used in the first and second generation thermal imaging systems.
