Detector circuit compensates for vidicon beam current variations

Signal detector circuit compensates for black level shifts in vidicons by dark current cancellation. It clamps the video signal to the dark current component of the signal. The device also compensates for background noise variation or transducer bias fluctuations in other repetitive pulse systems.

New television camera eliminates vidicon tube

Small, lightweight camera systems use solid state imaging devices in the form of phototransistor mosaic sensors instead of vidicon tubes for light sensing and image conversion. The digital logic circuits scan the sensor mosaic at 60 frames per second to produce pictures composed of a series of dots rather than lines.

IR vidicon scanner monitors many test points

Infrared /IR/ scanners are used in test systems that involve many signal paths from transducers to a central evaluation point. The scanner, an IR-sensitive vidicon, looks at the indicator panels of each subsystem of the equipment being tested and picks up the level of radiation from each IR source mounted thereon.
