Image motion model of azimuthally photography for satellite borne TDICCD camera

The 45-degree-rotated scanning mirror (RS mirror) was employed into the field of Wide-of-View (FOV) imaging with a scanning TDICCD camera by using the Coordinate Transformation method of building sub-satellite point image motion model with the Satellite Borne TDICCD camera. The imaging characteristics of the RS mirror and the Offsetting Image Rotation principle of the K Mirror were fully discussed. The effect diagram after offsetting image rotation with the K Mirror was further simulated to verify the rationality of K Mirror. Based on the light vector transformation matrix of the RS Mirror and K Mirror, the image rotation model was finally derived when bearing scanning TDICCD camera was used, which could support the theoretical foundation of subsequent image rotation analysis.
