A plurality of temperature dependent focal plane arrays operate without a temperature stabilization cooler and/or heater over a wide range of ambient temperatures. Gain, offset and/or bias correction tables are provided in a flash memory in memory pages indexed by the measured temperature of the focal plane arrays. The memory stores a calibration database, which is accessed using a logic circuit which generates a memory page address from a digitized temperature measurement of each of the focal plane array. The calibration database is comprised of an array of bias, gain and offset values for each pixel in the focal plane array for each potential operating temperature over the entire range of potential operating temperatures. The bias, gain and offset data within the database are read out, converted to analog form, and used by analog circuits to correct the focal plane array response. The output of each of the FPAs is multiplexed to a shared processing module and calibration data for each of the FPAs is accessed from the shared processing module.
