Abstract
Parallel phase-shifting digital holography (PPSDH) method can record dynamic three-dimensional events with higher spatial resolution than that of off-axis digital holography. In PPSDH, all amount of phase retardations are included in a multiplexed hologram and can be optically implemented by using a phase-mode spatial light modulator (SLM) located in the reference beam. The SLM can also compensate optical aberration caused by lenses, beam splitters, and air fluctuation as in adaptive optics. In this presentation, we review our experimental results using stationary two-dimensional object using a liquid-crystal on Silicon (LCOS) SLM.
