Videography based on computational optical scanning holography

Computational optical scanning holography (COSH), OSH using a spatial light modulator (SLM), has been proposed to realize a simple OSH setup. COSH, however, has yet to be applied for imaging a moving object due to the limitation of the frame rate of SLMs. In this research, a moving object is imaged by applying a fast SLM to COSH. The experimental result indicates the proposed method can take images with a frame rate of 1.25 Hz.
