Previous DOTF model is only for static, uniform motion and high speed harmonic vibration. In order to characterize random motion-blurred image, an arbitrary motion DOTF model was built, and it is a function of displacement s(t) of the motion image. The displacement function is no limits to any motion type, and we rigorous derived previously known DOTF expressions for static, uniform motion and high speed harmonic vibration, it is therefore concluded that our DOTF model can be developed for random motion. At last, an experiment was developed to verify our DOTF model.
