An Electro-Optical Test System

This paper describes how a host of sensors sensitive to X rays, ultraviolet and infrared, and to other electric or magnetic fields are distributed throughout a complex electronic system in such a manner that the system is continuously monitored to determine its condition of operability. The large quantity of data derived from these sensors are scanned by television techniques in order to meet the needs of rapid and automatic test. The test results are displayed on a cathode-ray tube in cyclogram fashion so that departures from normal operation may be easily and rapidly detected.
