After analyzing the characteristic of the rigid plane motion and the shortcomings of classical digital image correlation algorithms, the phase-angle position of the rigid body in the 2D image was characterized by 1D sequence signals using the method of equiangular sampling feature extraction based on circle windows. Then the generalized correlation algorithm for estimation of time delay based on wavelet transform was used to acquire the angular displacement. Finally the ultrasonic radiation force acted on the micro-component was determined by the relation between force and motion.
