Advances in investigations on static performance models of thermal imaging system

Investigations of performance models and their computer simulations are important links in thermal imaging technologies and provide the theoretical basis and analytical tools for system design, analysis, verification and genesis of new concepts. It is deemed as a key subject of investigations in various countries and a number of model versions have been successively presented in the USA. As China's national thermal imaging technologies are developing, investigations on this subject have advanced too. This paper reviews the state-of-art and progresses of the static performance models of thermal imaging system at home and abroad, gives an analysis of the concepts adopted and the characteristics of technological processing for several models, and points out the tendencies that deserve attention.
