Pagination or Media Count:
There are a number of training devices that can or do make use of photo-optical memories. Optical memories have application to other simulators such as forward looking infrared simulators and low light level television simulators. Recently an optical memory system was proposed as a cost-effective approach for the Observed Fire Trainer. NAVTRAEQUIPCEN has as its objectives improving photographic and optical technology to achieve advances in optical memory capabilities. One of the pieces of equipment used in this project is an Optronics International electrooptical scanning and writing system called Specscan. This equipment is being tested to determine its ability to change data formats, update data onplates and reduce cost of plate reproduction and updating through automated plate writing. This technical report analyzes the writing technique employed by Specscan and addresses the problem of nonuniform illumination within a writing cell.
