    摘要： An image dissector tube having a plurality of apertures thus providing a corresponding plurality of video signal pulses having a predetermined interval therebetween in response to a small input optical image as opposed to single random noise peaks in the output video signal. In the case of two apertures, the output video signal from the image dissector is delayed by substantially the interval between the paired video signal pulses and the delayed and undelayed signals passed to AND gate, thus providing a single output pulse in response to the paired pulses and supressing noise peaks.

    摘要： A search and tracking television system and method in which a storage-type camera tube is employed for searching a large field of view for a desired target, the image of the field viewed by the storage camera tube being displayed by one gun of a dual beam cathode ray tube. An image dissector-type camera tube is employed for viewing a smaller included field, and ultimately for tracking a desired target, and the image of the smaller field viewed by the image dissector tube is displayed by the other gun of the dual beam cathode ray tube. The image dissector tube is electronically and/or mechanically gimballed selectively to move the image of its field of view on the screen of the dual beam cathode ray tube so as to display the image of a desired target which appears in the field of view of the storage camera tube in the field of the image dissector tube. Once the target image has been so displayed, the image dissector tube is switched to its tracking mode so as to track the target thus acquired in its field of view.
