1 July 2003 Dynamic measurement of displacement with phase-shifting technique
Author Affiliations +
A simple spatial phase-shifting setup that uses a tiled mirror and a cat's-eye retroreflector is presented. It can be used in displacement measurement when high speed and accuracy are required. An experiment is carried out to demonstrate the feasibility of the method. A root mean square (rms) accuracy of better than 5 deg is obtained in ordinary circumstance. The system errors are also studied briefly.
