Abstract
Remote sensing infrared camera is two-dimensional thermal imaging equipment. In this paper, a new data acquiring and processing system of TDI infrared detector is given. This system is consisted of FPGA, ADC, SRAM memory, and so on. Low-pass filtering, pixel response non-uniformity correction, data synthesis and conversion of data output is implemented by a single FPGA. The SNR is improved by denoising algorithm based on oversample and comb filter. This system is easy to implement and can be applied in imaging device widely. The performance of imaging system is improved.
