Fiber Optics has been successfully employed to perform. the functions of image dissection and scanning in Facsimile Transmission. Two opera tional models have been developed and constructed on this program to incor porate the concept (Figure 1). One was designed to scan copy. 8-1/2 inches wide, the other, 18-5/8 inches wide. Both instruments possess the unique capability of continuously scanning copy of any length and generating a single which is suitable for a conventional GXC-5 Facsimile Recorder. Both instruments are open-throated so that copy wider than the scan area can be fed, though them.
