Research on the Thermicon Image Tube

Abstract

This report describes work on the development, design, construction and testing of the cooled Thermicon system, an infrared television system for night vision. Principles of operation and theoretical predictions of performance are given. The design and fabrication of sealed tubes and the problems of sensing layer preparation are described. A complete system, including optics, camera and cooling was built. A novel scheme for the enhancement of contrast by background subtraction was successfully implemented in a unit called a video correlator. The performance of the entire system was evaluated in outdoor night- time field tests, and also in a number of laboratory measurements. Two uncooled Thermicon tubes were also made and tested.
