Test Results of a High-speed Capping Shutter for Large-aperture Geodetic Cameras by M. S. Tavenner Pdf
Experiments were made with passive satellites for obtaining geodetic information using methods of stellar triangulation. Camera shutters for large-aperture cameras have presented a severe problem in timing. Using a contractor-developed capping shutter, a series of field tests was conducted with the Air Force's PC-1000 Geodetic Stellar Camera System for observations of the Echo I satellite. The report is concerned with the results of this test series and an evaluation of the capping shutter as adapted to the PC-1000 camera system. (Author).
