Transistorizing the Industrial Image Orthicon Camera

This paper describes the design of a fully transistorized image orthicon camera. Through the use of detailed circuit descriptions in areas such as the preamplifier, shading circuits and focus current regulator, the advantages transistors offer are pointed out. These advantages show themselves in the form of substantial reduction in weight, size, cost and operating power. Charts and photographs are used to describe in detail the sensitivity, capabilities and applications of such a camera. Schematics are used in describing pertinent circuit advantages.
