A novel non-uniformity compensating method for microbolometric focal plane array

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 proposed compensating method is simply configured and can easily and effectively be utilized to compensate the nonlinear non-uniformity of microbolometer array.
