A vidicon tube is a sort of 'reverse CRT'. Instead of sweeping a beam of electrons across a phosphor coating to display a picture, vidicon tubes sweep an electron beam across a photosensitive target to generate an image from the light striking the target. The 7038 is a fairly standard vidicon tube, with a length of 5.6 inches and a diameter of 1.1 inches. Vidicon tubes are still used today in some security cameras.
