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.

在研究检测对象刚体平面运动特点和分析传统数字图像相关算法局限性的基础上，采用基于圆周窗口等分角采样的特征提取方法，将二维图像中刚体的相角位置信息表征为一维采样时序信号，并通过基于小波变换的广义相关算法来估计位移前后特征序列的时延，得到刚体的旋转角位移，从而利用力与运动量的相互关系确定出作用于微构件的超声辐射力。
