摘要：
A high-speed digital holography based on a liquid crystal Spatial Light Modulator (LC-SLM) is presented. The production of multi-beam and control of their delay time can be achieved by controllable wavefront coding theory. In this paper, a Dammann phase grating was designed using a SLM to product multi-beam for extremely high speed digital holographic imaging. The required beam deflection could be obtained by adjusting programmable phase mask for controlling the spatial diffraction of input beam. The framing time is decided by interval beam angles and the distances between input plane and record plane. Theoretical derivate of generation multi beams based on SLM was proposed, and phase recover software was also made.
