Paper Abstract

Surface contouring by digital phase-shifting holograph system based on the LC-SLM is proposed in the paper. Special phase-shift is introduced in the reference beam by changing code pattern displayed on the LC-SLM. And the reconstruction quality of complex amplitude of object wave has been improved greatly. The surface contouring measurement can be realized by means of phase change introduced by rotating the object beam.
