Book Description
Image orthicons with structured targets were tested using a new cycled test set which separates the functions of exposure and read-out by a selected time interval. Resolution of image orthicons, when cycled in a manner corresponding to slow scan read-out, has exceeded 50 percent sine-wave response at 500 TV lines/inch. Possible means of increasing resolution toward the contract objective of 1500 TV lines/inch are discussed. Electron gun resolution, measured at high velocity, was nearly doubled during the year. Improvement was achieved by smoothing the mixed carbonate cathode coating. The procedures used to process targets are explained in detail. (Author).
