This paper describes a non-uniformity compensating method for microbolometric focal plane array. Through the analysis of the basic principle of conventional non-uniformity compensating methods for microbolometric focal plane array, we have pointed out their common fatal limitation unable to compensate the nonlinear non-uniformity of microbolometer array. Based on our previous constant power optimized bias, a novel and simple nonlinear non-uniformity compensating method for microbolometric focal plane array is proposed in this paper. The propose...
