Abstract

We describe and experimentally demonstrate a phase shifting method based on the lateral displacement of a grating implemented with a twisted-nematic liquid-crystal spatial light modulator. This method allows an accurate implementation of the phase shift without requiring moving parts. The technique is implemented in a Mach–Zehnder digital holography setup in which the field transmitted by the sample object freely propagates to the hologram plane.
