NOVEL IMAGE-DISSECTOR CAMERA-TUBE FOR SURVEILLANCE APPLICATION INVESTIGATION.

Abstract

An image-dissector has been built with an electrostatically variable aperture. This device gives a 5-to-1 change in resolution with a corresponding improvement in signal-to-noise ratio at low light-levels. A prototype night-surveillance system which could incorporate this device has also been constructed. The system incorporates an image-dissector which is scanned synchronously with a laser beam. It is shown that the ranging distance and accuracy is mainly limited by the laser power and the oscillating-mirror system used to scan the laser beam. The range-gate achieved was about 250 yards up to a distance of 600 yards. (Author)
