FIELD: technical physics.
SUBSTANCE: system can be used for getting images of quick-going processes in open photographic material on base of shade photography; it can be used during aero-ballistic surveys, in particular, when investigating conditions of tested models. Device has pulse light source and camera with open photographic film. Camera is made in form of light-penetrable basket with opening turned to light source mounted along optical axis of system. Diffuse screen is placed between camera and light source at distance of l from opening of camera, which distance is defined by required scale of image. Shade photography of quick-going process can be made onto wide-format photo-film; process is accomplished with background illumination.
EFFECT: elimination of influence of natural illumination onto process of registration; simplified design of registration system.
