Abstract
Two methods of high speed holocinematography are described using spatial or patial frequency multiplexing for image separation. The experimental devices operate in the range of10 000 to 20 000 holograms per second with a total number of holographic frames of four to eight. Spatial multiplexing is achieved by a rotating disk with apertures placed directly in front of the holographic plate. Spatial frequency multiplexing is obtained with the aid of a special.acousto-optic beam splitter and deflector unit. Objects investigated by both meth-ods are bubbles moving in acoustically generated cavitation bubble fields as well as bubbles formed after laser-induced breakdown in water.
