2017-02-28 · Compared to traditional phase retrieval approaches, our SPR algorithm uses over an order of magnitude less pixel measurements while maintaining suitable reconstruction quality. We use an on-chip holographic video setup with pixel sub-sampling to experimentally demonstrate a factor of 5.5 increase in sensor frame rate while monitoring the in vivo movement of Peranema microorganisms. An efficient method of reconstructing the phase distribution for off-axis digital holography is proposed using hologram multiplexing with hologram rotation and complex encoding. A first hologram and a second 180° rotated hologram from a hologram sequence are first assembled into a synthetic hologram using the complex encoding method. Then, digital reconstruction processes, including Fourier A novel phase modulation method for holographic data storage with phase-retrieval reference beam locking is proposed and incorporated into an amplitude-encoding collinear holographic storage system. Unlike the conventional phase retrieval method, the proposed method locks the data page and the corre … 2021-04-21 · Optics Express (OSA) has published an article on Dynamic Sampling Iterative Phase Retrieval for Holographic Storage.
