AB - This article proposes a real-time calibrating(non-uniformity correction) method for the bi-directional scanning infrared TDI imaging load on the aerospace platform. The method is completed through efficient cooperation of a scanning mechanism, a real-time calibration device, and an image preprocessing device, by employing the scanning blanking period for bi-directional calibration. The image preprocessing device uses high-performance FPGA as the core processor, which can perform flexible working sequence control of the detector, accurate detection of calibration synchronization signal, fast acquisition of calibration data and efficient pipelining data processing. Moreover, by using the Micro Blaze IP core, the preprocessing device can calculate the calibration coefficients of two-point correction in real time and also fulfill communication with the host computer. Proven by practice, the calibration method of the bi-directional infrared TDI detector described in this paper has high practical value with the advantages of high processing speed, significant effect, and high system integration.
