Abstract

In this paper, a hybrid method of in-line and off-axis digital holography is proposed. Off-axis digital hologram and in-line hologram are recorded. The approximate phase distributions in the recording plane are obtained by constrained optimization approach from the off-axis hologram, and they are used as the initial value in the iterative procedure of the phase retrieve of in-line hologram. For static objects, the proposed method can be implemented with a single laser and dual shots. For dynamic objects, it can be implemented with dual-wavelength lasers and a single shot. It can achieve high-resolution, wide field-of-view holographic imaging.
