Description
A photo-dielectric tape camera is a type of television camera which combines the features of an image sensor and an electrostatic tape recorder in one package. Photo-dielectric tape (usually abbreviated to phototape or dielectric tape) is the essential part of a dielectric tape camera; it includes both the photosensitive medium and the storage medium. Optical images sensed by the camera are stored directly on the dielectric tape in the form of a charge pattern. The stored information can be retrieved immediately or retained for as long as several months.
Two types of dielectric tape camera have already been built by the Astro-Electronics Division of RCA as a result of programs sponsored by the National Aeronautics and Space Administration and the Air Force. One type, a 35-mm, panoramic, slit camera* has been developed and space qualified for the Goddard Space Flight Center of NASA under Contract No. NAS- 5-2503. Another type, a 70- mm, high- re solution camera, has been built as a laboratory model for the Air Force Avionics Laboratory of Wright-Patters on Air Force Base under Contract No. AF 33(657)-11485. These cameras are shown in Figure 1 and 2, respectively. In addition, several other types of dielectric tape cameras are in conceptual form.
