Abstract: Acousto-optic devices comprising a transducer bonded to an acousto-optic medium having improved bonds are made by a process whereby the surfaces to be joined are first roughened, a primer metal layer is coated onto the acousto-optic medium, which primer metal is the metal which is chemically bonded to oxygen in the acousto-optic medium, the primer layer is cooled, a layer of a conductive metal and a layer of indium are deposited onto both surfaces to be bonded and the indium layers pressed together in a vacuum.

Abstract: A page composer is disclosed for translating a plurality of serial electrical binary information signals to a pattern of light on an opto-magnetic recording medium. A plurality of radiofrequency oscillators each has a control input coupled to a source of serial binary information signals, and an output coupled to an electro-mechanical transducer at one end of a respective one of a plurality of acousto-optic columns. Sonic information is thus propagated serially through the columns as information cells which contain a sonic burst to represent one binary value, and no burst to represent the other binary value. Incident light from a source is directed through the columns at an angle with the sonic wavefronts therein to cause diffraction of the light. The source of light is pulsed when the columns are filled with serially-supplied sonic information. Cells containing a sonic burst cause a diffraction of the light passing therethrough, and cells not containing a sonic burst permit the light to pass directly therethrough.
