Electro-Optical Rectifier (EOR) Update Study

摘要

A study has been performed to determine means of improving the Electro-Optical Rectifier (EOR), which is an optical projection instrument for rectifying oblique frame, strip, and panoramic photography. The study consisted of an engineering analysis of the present system, study and evaluation of alternate system designs, and development of a preliminary design for an improved EOR system. Preliminary design features include use of a dedicated digital computer to perform both the rectification calculations and system control functions in real time, a disk operating system, a digital servo system, new carriage drive gear boxes, high-performance motor/techometers, and a new servo drive that permits computer control of drum velocity.
