In order to expand the application of a high-speed rotating mirror camera, some high-speed photographic techniques including a magnification optics system, a turning mechanism, a transmitting-type schlieren system and a multi-channel fibreoptical sensor have been developed. The detail of these techniques and results from experiments are described in this paper. It's well known that a high-speed rotating mirror camera is an important optical instrument with a high space-time resolution. It has widely been used in fields of explosion mechanics, high-velocity impacts, plasma physics, electrical pulse discharge and so on. In 1958, Northwest Optical Factory and the others in China started to develop the camera and to produce it on a small scale for use. In 1962, Xian Institute of Optics and Precision Mechanics was established. After that time, most of the researching work about high-speed rotating mirror cameras have been charged by the Institute. However, the others have also made some special cameras according to their own need. In order to expand the applications of high-speed rotating mirror camera, various additional optical equipment has been made to satisfy different demand. A part of additional equipment is as follows.
