Abstract

Phase-shifting digital holography has a feature that a hologram can be acquired with a spatial resolution of an image sensor. The interference images should be acquired at multiple times while the phase-shifting is given to the reference light. Therefore, some idea for imaging a moving object have been discussed. The phase-shifting digital holography with burst-imaging method is proposed for imaging a moving object. The phase-shifting digital holography at 460 μs is demonstrated by using a high-speed camera and a high-speed phase modulation based on a piezoelectric element.
