Abstract :
This paper contains a description of a Dielectric-Tape Camera System. The parameters of the system are described for a camera orbiting at 600 miles which is capable of complete earth coverage every 24 hours. The system and design effort discussed was divided into four major areas: the tape, electron optics and eletron guns; the circuits including video, power supplies, motor drive circuitry, and command, control and logic circuitry; the mechanical design including the tape transport, mirror mechanism, optics and camera enclosure; and three items of special test equipment. The special test equipment which was designed to provide operational evaluation of the system includes a command and timing simulator, an optical simulator, and a display device. The paper also includes a brief description of the system tests performed and a discussion of the test results.
