Infrared Vidicon Development

Abstract

The objective of the program was to demonstrate the feasibility of using metal-silicon Schottky barrier diode arrays in the retina of an infrared vidicon. Such arrays promise to be substantially more uniform in this application than other available approaches. Since retina non-uniformities are the major factor limiting system sensitivity, improvements in uniformity would permit substantial gains in system performance. To demonstrate these improvements, it is necessary to employ a demountable camera tube with which a number of retinae of varying designs can be evaluated (keeping operating parameters such as electron optics, retina temperature, etc., constant). Such a demountable camera tube has been built and tested, and is currently being used in on-going studies of infrared imaging using metal-silicon Schottky barrier infrared vidicon retinae. The tube can be operated in the high beam velocity mode (either positive or negative variation), or in the low beam velocity mode.
