For a normal microbolometric focal plane array, the microbolometric infrared responsivity varies with its substrate temperature fluctuations because of the semiconductor characteristics of the microbolometer array. The relationship between the microbolometric infrared responsivity and substrate temperature is theoretically discussed in this paper. Above the discussion, a new substrate temperature compensation method is proposed for microbolometric focal plane array without TEC. The microbolometric focal plane array is based on a kind of high-sp...
