Paper Abstract

The priority associated with U.S. efforts to increase productivity has led to, among other things, the development of Electronic Vision Systems for use in manufacturing automation requirements. Many such systems combine closed circuit television cameras and data processing equipment to facilitate high speed, on-line inspection and real time dimensional measurement of parts and assemblies. These parts are often randomly oriented and spaced on a conveyor belt under continuous motion. Television imagery of high speed events has historically been achieved by use of pulsed (strobe) illumination or high speed shutter techniques synchronized with the camera's vertical blanking to separate write and read cycle operation. Lack of synchronization between part position and camera scanning in most on-line applications precludes use of this technique and dictates that another approach be utilized. Unique inject-inhibit capability of General Electric Company's Charge Injection Device (CID) imager will, when interfaced appropriately with Xenon strobe illumination, provide asynchronous stop motion imagery and facilitate dimensional measurement at rates of up to 900 parts per minute. OPTOMATIONIM Electronic Vision Systems incorporating this capa-bility have been operating in factory applications for now, in excess of three years. Operation of the CID Solid State imager will be reviewed in this context along with the system equipment, and possible future developments will be discussed.
