Embodiment Construction
[0035] Below in conjunction with the accompanying drawings, the present invention will be further described in detail by taking the refrigerated long-wave 640x512 focal plane detector SCORPIO-LW produced by the French SOFRADIR company as an example, but the scope of protection of the present invention is not limited to the following embodiments.
[0036] This type of detector is currently often used to build civilian observation infrared imaging systems. The final video output of the imaging system in this embodiment uses standard digital CameraLink video output with a frame rate of 40 frames per second. For this type of detector, its readout circuit can provide the fastest analog original signal output of 210 frames per second. The steps of the present invention are described in detail below:
[0037] A offline calibration:
[0038] A1 combined with figure 1 , first determine the number of detector integration times and the number of groups of non-uniformity correction para...
