High-speed phase-shifting incoherent digital holography (invited)

Applied physics B, 2023
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.
