EXPERIMENTAL RESEARCH OF PHASE-SHIFTING DIGITAL HOLOGRAPHY BASED ON SPATIAL LIGHT MODULATOR
Rong Li · Journal of South China Normal University · 2009
An experiment system of phase-shifting digital holography was designed which uses the digital object produced and controlled by spatial light modulator(SLM) in light path of phase-shifting digital holography.The record of digital holograms of digital object displayed on SLM and the reconstruction from digital holograms were realized.Experiment results reveal that the phase-shifting digital holography is better than the digital holography,and the phase-shifting digital holography based on SLM will open more space for the phase-sifting digital holography in future,because it has many characteristics such as digital objects,variable parameters,moving objects,etc.
