设计了刚体平面位移测量系统。通过散斑图像的互相关计算平面位移。测量结果表明，在300 µm位移范围内，平面位移的绝对误差小于±14 µm，相对误差小于±6.25%。
A measurement system of plane displacement in rigid body was designed. Plane displacement was calculated by the cross-correlation of speckle image. Measurement results showed that the absolute-error and the opposite-error of the plane displacement less than ±14µm and ±6.25% respectively, under the displacement range of 300 µm.
