Abstract

A historical review of Japanese explosion studies from a point of view of highspeed photography and a simple elucidation of explosion are presented. Proper understanding is indispensablein taking a high-speed photography for analysis. Gas evolution,flame ignition,flame expansion,smoke generation,shock wave formation,its passage, structure breakage, rock movement etc. are the important feature of explosion to be studied with a high-speed camera. Examples referring to the above items are abstracted from Japanese literature. The first instance is a study on muzzle flames with a rotating disk camera which uses photographic dry plate. A Cranz-Schardin system then appears. After the War adding to the above cameras 16 mm cinecameras are widely brought into use. Rotating mirror type cameras are also used in shock wave studies. Besides X-ray flash sources are effectively used.
