Single-exposure phase-shifting digital holography using a random-phase reference wave

摘要

We propose a single-exposure phase-shifting digital holography based on a wave-splitting method using a randomphasenreference wave. A random-phase reference wave gives random-phase distribution on the digital hologram.nUsing the amplitude and the phase distributions of the reference wave, the fully complex amplitude of the objectnwave is obtained. The proposed method requires not devised optical systems but ordinary imaging devices, such asnCCD cameras. A preliminary experimental result is given to confirm the proposed method.
