Optimum method of choosing FPA detector basic model

In order to solve the amount variety development problems of focus plane array (FPA) thermal imagers the variety optimization ways of FPA thermal imagers are researched out in this article. The optimum factors of FPA thermal imagers are determined which are sensitive to the performances and applications for FPA thermal imagers, such as materials, radio sensitivity, work temperature, obtainable level, costs etc. The knowledge models of the material choosing field, performance determination, specification choosing field etc. for optimal guidance are presented. The matrix mathematics models for the optimization in quantitative ways are researched out. A set of optimization method for finding detector basic models with quantitative and qualitative ways is built. Four FPA detectors are chosen out as basic standard detectors from more than 130 type detectors. The four FPA detectors can cover most of military applications. The optimization method can be used in the optimization of other products.
