Realization of Nonuniformity Correction for IRFPA Based on FPGA Using Function Fitting
函数拟合红外焦平面阵列非均匀性校正FPGA实现研究

Upon considering the engineering practice of the nonuniformity correction of infrared focal plane array (IRFPA), a correction algorithm based on function fitting is designed.The nonuniformity correction system of IRFPA is realized by using large-capacity high-speed field programmable gate array (FPGA) device . The system can effectively adapt to the broad dynamic range and non-linearity of response characteristic of IRFPA with some advantages such as small size, fast speed and high correction precision.
