摘要： This disclosure depicts a virtual image viewing system including a component to be worn by an observer in the manner of spectacles, the system being responsive to a source of video signals and associated deflection signals and to a laser beam for establishing a virtual optical image representing said video signals which is visible only to the observer. In one embodiment the system includes flying spot scanning means which is responsive to the deflection signals and which receives the laser beam for deflecting the beam in two dimensions and for converging the beam to form an unmodulated flying spot raster. A Bragg light-sound interaction cell constituting the component to be worn is responsive to the video signals and receives light from the flying spot raster for modulating the received light to develop a virtual image representing the video signals which is visible only to the observer. Other embodiments are depicted.

摘要： The present invention relates to graphic reproduction systems capable of printing onto a photosensitive material or transferring to a substrate graphic forms such as those displayed upon the screen of a cathode-ray device. According to the present invention there is provided a graphic reproduction system wherein the writing assembly comprises : a quasi-monochromatic light source, acousto-optical modulator means transmitting the radiant energy beam issuing from said source and acousto-topical means associated with anamorphotic means of prism-type, for deflecting the modulated beam emerging from said acousto-optical modulator means. The invention allows the graphic reproduction of data displayed upon the screen of an arbitrary display device, as well as the distant graphic reproduction of arbitrary graphic forms.

摘要： An acousto-optical light deflector comprised of a piezo-electric sound transducer adapted to receive a high frequency signal so as to generate ultrasonic sound waves and a crystalline sound medium coupled with the sound transducer to receive the sound waves and a beam of light so that the sound waves within the sound media forms a phase diffraction grating for the light beam. The sound transducer is preferably composed of a single crystalline lithium sulfate monohydrate and the sound media is preferably composed of Alpha -iodic acid.

摘要： In an acoustooptic light deflector, frequency modulated acoustic shear waves propagate in the (110) direction in a paratellurite TeO2 body and the light beam, which is elliptically polarized, propagates at a small angle to the optic axis of the TeO2 body. The optical activity of paratellurite TeO2 is exploited to produce an inflection point in the angle of incidence-versusacoustic frequency characteristic of the deflector. The center frequency of the acoustic wave is made to be approximately equal to the inflection point frequency in order to obtain larger deflections at lower acoustic power than heretofore possible. In a preferred embodiment the TeO2 body is grown by the Czochralski method from a starting material which is at least 99.9999 percent pure in order to obtain paratellurite TeO2 crystals of low optical scattering loss as well as low acoustic absorption loss.

摘要： An optoacoustic surface-wave device, using the principle of optical tunneling, which provides for direct amplitude modulation of a light beam by the local amplitude variation of an acoustic surface wave. The optoacoustic device uses an acoustic surface wave to locally perturb the boundary conditions at a reflecting interface, between two elements, at least one of which is a prism, and to locally modulate the light. The basic optical tunneling interaction cell includes two prisms, at least one of which is a triangular prism, separated at the interface by a small distance, for example that provided by thin-film spacers. The acoustic surface wave is propagated along one of the surfaces at the interface of the two prisms, while the light is incident at an angle, generally perpendicularly, to one of the faces of a prism.

摘要： Light-beam scanning angles obtainable from light-sound interaction are increased by introducing dispersion of the sound waves. In one general approach, the sound waves are passed through a fixed grating or otherwise through a medium which is dispersive by reason of its character. In another general approach, vibrational dispersion is obtained by launching a longitudinal wave in response to either a shear wave or an extensional wave.
