Abstract

The infrared focal plane array (IRFPA) imaging system is the trend of IR imaging technology. However the most difficult problem associated with the IRFPA is intrinsic spatial photo-response nonuniformity. Practicable and real-time nonuniformity correction (NUC) is a key technology in the application of IRFPA. The main specifications and parameters of IRFPA nonuniformity are researched, and a real-time new nonuniformity correction method by using the field programmable gate array (FPGA) technology is presented in this paper. It has the advantage of large dynamic range, small storage capacity, high processing speed and high corrective accuracy, etc. Then the correction principle and main steps are described in detail. The block diagram of hardware circuit and the working processes were introduced. The experimental results are satisfactory, showing advantage of this method.
