Abstract : A luminescent display device suitable for operation with airborne sensors that provide an endless raster line scan has been assembled and tested. It consists of a continuously moving flexible plastic belt coated with a long-decay photoluminescent phosphor, and an ultrasonic ultravoilet light modulator. The phosphor is excited to luminescence by the video-modulated ultraviolet light spot. An image is formed by sweeping the light spot perpendicular to the direction of belt motion. The system has zero flyback time and provides an instantaneous inflight examination of data for the image of a flight path. The phosphor-belt light output is also sufficient to permit image reproduction on a Lumincon TV-type of display, and is well suited to operation as an integral part of a sensor system, or at a distance by a communication link.
