VFK-ÚVOJM High-Speed Framing Camera
A double-drum, high-speed framing camera capable of photographing fast-moving mechanical and electrical machinery for quantitative analysis produces 1304 pictures, each 5 by 8 mm on a 1850-mm length of unperforated 35mm film. The camera can record at 8000 to 42,000 frames/sec, with an aperture ratio of f/7, and resolves 80 lines/mm. Synchronization of image motion with the moving film is accomplished by rotating an inner drum carrying secondary objective lenses at the speed necessary to cause the image to move at the same velocity as the film on the outer drum.
