Paper Abstract

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 300μm.
