Implement of Pyroelectric IRFPA Nonuniformity Correction Using FPGA

Nonuniformity exsists in all IRFPA detectors,and it limits the performance of infrared imaging detectors.Here we analyse the cause of the nonuniformity for IRFPA at first, then give some methods for NUC.At last the design of NUC for pyroelectric IRFPA using FPGA is presented.
