Improved Developmental One-Inch Vidicon for Television Cameras

An improved developmental 1-in. vidicon for use in live and film pickup is described. The design features of this tube result in a higher degree of uniformity of characteristics from tube to tube and, therefore, make it possible to obtain better register in color cameras. These features are a result of the development of an extremely uniform photoconductive surface and precision design. — Methods of compensation for beam-landing errors, which are responsible for most of the nonuniformities in signal output of vidicons, are explained. This paper describes a method of operation which, with proper circuit design, can be utilized to obtain the higher sensitivity required for live pickup. Tentative performance data are given and compared with those for present vidicon-type camera tubes.
