An ideographic optical typesetting machine employs a stationary character matrix comprising 10,000 holograms, a laser light source and a beam deflector system enabling light from the laser to be scanned over the matrix. The holograms are so recorded that when scanned by the beam they cause an image to be reconstricted in a common location, where a suitable receptor is located. As described each image contains more than one print symbol, and the receptor is shiftable to receive any one of those symbols as required. In all 250,000 print symbols are stored on the matrix. Additionally, each image includes code signals for the control of scanning and exposure time. |
