We present single-shot phase-shifting digital holographic microscopy using space-division multiplexing of holograms. The technique has the capability of clearly imaging the temporal change of a three-dimensional movement, μm-order structures, and the phase distribution of an object. The experimental result for a moving object was demonstrated.
We demonstrate high-speed parallel phase-shifting digital holography capable of three-dimensional measurement of a dynamically moving object. We constructed the recording system by using a quarter-wave plate and a high-speed polarization-imaging camera. Moving pictures of two vibrating elastic bands located on different depth plane were clearly and individually reconstructed by the technique.
