Development of Two-frame High-speed Holography System

Abstract

A new twin-pulsed high-speed holography system which can record two frames continuously, was developed for the recording of high-speed phenomena with high temporal resolution. Two phenomena which occur at different time are recorded in one hologram, and after photographic processing, the images of the phenomena can be reconstructed independently. Using this system, diesel fuel injected into the open atmosphere was recorded, and spark ignition of fuel gas was also recorded by double-exposure holographic interferometric method.
