Abstract
A technique of single-shot phase-shifting interferometry called as parallel phase-shifting digital holography is described. This technique records multiple holograms required for phase-shifting digital holography using space-division multiplexing technique. The authors constructed a system based on the parallel phase-shifting digital holography consisting of a Mach–Zehnder interferometer and a high-speed polarization imaging camera. High-speed motion pictures of three-dimensional image and phase image of dynamically moving objects at the rate up to180,000 and 262,500 frames per second were achieved, respectively, for the 128 × 128-pixel images.
