High-speed photographic camera-chronograph ROTA-MIR with pulsed light source

High-speed photographic camera ROTA-MIR is described which is capable of registering fast processes both in chronographic and frame-by-frame regimes. The latter regime is obtained using object irradiation by a shot pulse light source. The camera has a gas-turbine drive mirror rotor with rotation speed up to 150 thousand revolutions per minute. Entrance lens optics is changeable and provides discrete magnifications 5x, 1x and 0.55x. Two types of photographic films, 35-mm and 70- mm, can be used in the camera.
