For space-borne remote sensors with wide field of view, images on focal planes motion deform nonlinearly as well as vary with time due to the affects from satellites orbital motions, attitude maneuverings, jittering, earth ephemeris and geometrical characteristics, optical designs and so on. The distribution of image velocity field determines the exposure integration accurate for the image formation procedure so as to affect the image qualities. A new method is proposed that it focus on to found the image motion velocity field mathematical model which especially appropriate to wide field of view sensors through analyzing the problems of image formation for apparent kinetic spatial object with smooth curved surface. Analytical formulas of image velocities are deduced. The algorithm is proved not only to be precise but also efficient. It can be employed as the dynamic imaging algorithms for embedded computers of orbiting payloads and their instrumentations. Based on this research, it′s concerned that an optimized approaches for charge coupled device (CCD) detectors exposure integration control via image velocities matching along with deflect angles compensations as the strong nonlinear image velocity fields.
