A High-Speed Focal-Plane Shutter Framing Camera

S. J. Jacobs, J. D. McLanahan, E. C. Whitman

A rotating mirror framing camera which operates in the million frame per second range is described. The camera is based on the principle of the focal-plane shutter, making use of six shutter slits to record 216 frames in six rows of images. Each image measures 24 by 18 mm. The geometric aperture of the camera is about f/20. Provision is made for varying the exposure time to frame time ratio by selection of the shutter slit widths. The method of phasing the shutters to obtain higher framing rates with improved precision of position-time data in the records for a given rotating mirror size and speed is described.
