Abstract
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.
Claims21
A character matrix for an optical printing or typesetting machine which matrix comprises a plurality of holograms each of which stores an image containing print symbols and control signals.
An optical printing or typesetting machine for ideographic writing systems comprising in combination (a) a source of substantially monochromatic radiation, (b) a deflector system which deflects radiation emanating from said source, (c) a character matrix which is fixed relative to said source during printing or setting of a symbol and which includes a plurality of holograms each of which when illuminated by radiation emergent from said deflector system causes the reconstruction at a common image field of a character image consisting of an array of symbols, (d) control means controlling said deflector system to direct radiation selectively towards any one of said plurality of holograms, (e) a receptor settable to respond to any one of a given number of distinct regions of said common image field and thereby receive a given symbol of the corresponding array upon illumination of any one of said holograms, (f) a shift mechanism which controls the setting of said receptor, and (g) composing means coupled to said receptor.
