Single-shot Fresnel incoherent digital holography based on geometric phase lens

Single-shot and incoherent imaging are two important properties for digital holography technique to extend its application range. In this paper, a simple and compact in-line Fresnel incoherent digital holographic recording system with capability of single-shot and three-dimensional imaging is proposed. A GP lens is used as the common-path interferometer based on its special wave separation property. Parallel phase-shifting holography is used to achieve single-shot operation by using a polarization imaging camera together with space-division multiplexing. The capability of the proposed technique and the setup was experimentally confirmed by images of two standard test charts.
