A three-inch image orthicon with electrostatic motion-compensation was developed and tested. It measures 21-inches overall, of which 7-12 inches are taken up by the image-section. Resolution is of the order of 17 line-pairs per mm. Capabilities include the tracking of translatory motion of images projected on photocathode within a 1-116 inch circle. In this process, storage gains of over 40db in light-sensitivity have been realized. Image-deflection requires a balanced voltage of 500 volt per terminal. A feedback-dc-amplifier is described which operates on a single-ended input of 10 volts. In circuit, its square-wave response extends beyond 300 kilo-Hertz, including d-c. Image misregistry follows an r to the 3rd power-law with radius r. Errors of superposition stay below 0.8, and 2.8, respectively, within areas of 916-inch and 1-116-inch diameter on photocathode. Several types of test-equipment are described. This includes gating-pulse generators, electronic switches of the type DPDT, and a special film-transport for continuous-motion at one frame per second, complete with synchronous slow-scan circuitry.
