A kind of high-rate and low-noise information acquisition system for French cooled 320×256 HgCdTe long wave infrared focal plane arrays MARS LW K508 was designed. The system consists of detector drive, signal processing, data acquisition and sequential control, image transmission and processing modules. Experimental results show that the frame frequency of the system can be up to 200 frame/s, the RMS is 0.7-0.8 mV (300 K) and images after nonuniformity correction are clear, which can be used in the high-end thermal infrared focal plane field such as surface thermal infrared spectral detection and high-speed infrared surveillance and imaging.
