A new arrangement for a high-speed rotating-mirror framing camera using mirror strips instead of lens strips as framing stops is described. The design is especially simple when a few frames close together in time are required. A camera which takes 14 frames resolving about 150 line pairs across the frame at a rate of 10,000,000 frames per second, or 14 frames resolving 250 line pairs at a rate of 5,000,000 frames per second is also described. The effective exposure time is 80% of the time between frames, and the camera operates at effective aperture of f/20.
