Abstract
Abstract We propose high-speed incoherent digital holography with a recording speed of 1,000 fps, which is designed for the three-dimensional (3D) motion-picture measurement of moving objects with high temporal resolution. We adopt single-shot phase-shifting incoherent digital holography, a high-speed polarization-imaging camera system, and a palm-sized self-interference interferometer designed for spatially and temporally incoherent light, to implement a high-speed phase-shifting incoherent digital holography system. High-speed four-dimensional (4D) (3D and time) measurement capability is experimentally demonstrated, using the constructed incoherent digital holography system set on a wagon and a daily-use white-color light-emitting diode.
