   A program model and relative software tool has been developed allowing to simulate transformations of different physical nature the initial image undergo while passing through electro-optical path of IR TDI system. The developed software is intended to be an everyday-practice focal plane arrays engineer's tool for optimizing PD and multiplexer structure and tradeoff analysis. The software is especially useful in the cases of relatively complex arrangement of photodetector apertures, and/or when image motion trajectory in the focal plane is "non-ideal" (e.g., skewed with respect to its normal direction, or waved-form), which are the cases in practical systems. The preliminary results on the image processing in practical middle-wave infrared TDI system are given demonstrating the influence of various system parameters on final image quality and confirming the validity of the model.
