Television pickup tubes which use a low-velocity electron beam for scanning a photosensitive target offer the possibility of avoiding some of the limitations of devices which use a high-velocity beam. Some of the advantages of the low-velocity beam are: (1) low level of spurious signals, (2) high maximum signal output, and (3) high efficiency of conversion of light into signal. The major problems encountered are: (1) ways to keep the beam in focus and (2) ways to obtain undistorted scanning of… Expand
Television Camera Tubes: A Research Review
Publisher Summary This chapter presents a research review of television camera tubes. In an ideal tube, the sensitivity, resolution, and contrast discrimination would be limited only by theExpand
A New Magnetic-Focus Static-Deflection System for a Sincle-Tube Color Camera
TLDR
A new magnetic-focus static-deflection system has been developed under a program of exploration of possibilities of designing vidicon tubes to make a focusing and deflection system which will have high quality electron optical characteristics with simple construction and require low power consumption.
