Improved camera-tube performance with pulsed operation

Improving image-sensing parameters is a high-priority goal in the development of camera-tube (vidicon) television systems. In past efforts to enhance video output from these television systems, the emphasis has been on multiple-frame integrations of a single scene and computer data processing of the recorded video. In the electronic technique discussed in this paper vidicon performance is improved by synchronously controlling the sensing-layer bias. Specifically, camera-tube sensitivity and dynamic response are significantly increased while other tube parameters remain unaffected.
