Introduction to the Vidicon Family of Tubes

Part of the Optical Physics and Engineering book series (OPEG)


The term vidicon1 is frequently used as a generic term for a photoconductive camera tube. Vidicon is also a name that partially describes return-beam vidicons, lead oxide vidicons, and silicon diode vidicons. The latter device has a photosensor comprising a mosaic of silicon diodes and the lead oxide tube is presumed also to be a junction-type device. This chapter will be restricted to the nonjunction type of photoconductive tube, while the others are subjects of later chapters. Figure 1 shows a schematic cross section of such a tube. The photoconductor is a continuous layer with a transparent electrode on the faceplate side. The scanning beam is the same low-velocity type used in most camera tubes, and usually the signal is taken from the current deposited on the target instead of from a return beam.
