Abstract
A prototype imaging system consisting of a monolithic sensor array of pyroelectric elements has been constructed which is capable of imaging visible, infrared and x-radiation. The image sensor is a true flat-panel, self-scanned device which generates a video picture of radiation intensity patterns at the usual television rate of 30 frames per second. The detector material is ceramic lead-zirconatc-titanate which has an individual spot responsivity of 1 V/W. The video information is extracted from the sensor mosaic by digital scanning and video coupling circuits which are connected to the array by row and column address electrodes. The electronic circuitry consists of low cost, low power integrated circuits. The initial prototype system incorporates a 5 × 5 element sensor matrix and a large scale device composed of an array of 2500 spots is currently under construction.
