SWIR (Short Wave Infrared) is the important wave band in the field of infrared detection application. Aiming at the video imaging application background of SWIR in the certain conditions such as thin fog, haze, night and so on, the full project design of an area array steering video imaging system is presented. The design, developing and testing of the prototype are fulfilled based on short wave infrared 320×256 InGaAs detector. Nonuniformity correction is implemented on FPGA hardware to meet the real-time requirement of video-level data stream output. The results of experiments prove that the design of the imaging system circuits is reasonable and effective. The noise level is quite low, the dimension is small. All the specifications meet the need of application requirement. The performance of detector is good with video-level data output. Continuous short wave video with high quality is obtained.
