Patent number: 6538690Abstract: Pixel clock and beam scan timing of an acousto-optic scanner are controlled by an acoustic velocity-driven, phase locked loop containing an adjustable voltage controlled pixel clock generator, which is controlled by a detector that produces delayed and attenuated replica of the excitation waveform applied to an ATWL scanner used to scan a light beam across a workpiece. In a first embodiment of the invention, an end-of-cell transducer converts the pressure induced traveling lens into an electrical signal replica of the excitation input. In a second embodiment, an end-of-scan optical pick-off monitor is employed to detect the scanned optical spot as it crosses its field of view.Type: GrantFiled: March 8, 2000Date of Patent: March 25, 2003Assignee: Harris CorporationInventors: Robert M.

Patent number: 6487324Abstract: An acoustic impedance-matching transformer includes a tapered acoustic energy transmission (metal) block, having an acoustic impedance less than that of a piezo-electric transducer in a metric direction toward that of the acoustic propagation medium of the waveguide, and by an amount that allows tailoring of the relative spatial dimensions of mating surfaces of the transducer and the block, so as to provide efficient broadband coupling of acoustic energy. The surface area of the end face of the block engaging the transducer is a corresponding fraction of the area of the transducer. The tapered block focuses acoustic energy toward the input aperture of the waveguide channel. The taper is determined in accordance with difference between the acoustic impedance of the aluminum block and that of a second acoustic wave propagation element, such as a quarter-wave section of plexiglass, interposed between the waveguide channel and the tapered block.Type: GrantFiled: June 29, 2001Date of Patent: November 26, 2002Assignee: Harris CorporationInventors: Robert M.

Patent number: 6052215Abstract: A solid state acoustic travelling wave lens comprises a thin core layer of acoustic and light transmissive material, such as crystalline quartz, compression-bonded between a pair of outer or cladding layers, such as fused silica, having an acoustic velocity that is only slightly higher than (e.g., less than five percent of) that of the core material. The acoustic mode field characteristic of the weakly guiding device contains no spatial variations caused by Fresnel diffraction in an unguided wave device. In a second embodiment, shear stress coupling between the core and cladding layers is inhibited by interposing very thin liquid boundary layers between the core layer and the cladding layers. Such thin liquid boundary layers, which are relatively more compressible than the core and cladding material, allow longitudinal waves to be transmitted across the core/cladding boundary (through the liquid), but prevent transmission of shear waves therebetween.Type: GrantFiled: January 22, 1999Date of Patent: April 18, 2000Assignee: Harris CorporationInventors: Robert M.

Patent number: 6043924Abstract: An acoustic traveling wave lens structure for an acousto-optic scanner comprises a confined height fluid-containing channel, upon which a scanned optical beam to be modulated by a acoustic traveling wave is incident. The channel is bounded by spaced-apart walls that extend between a first end of the scanner channel, to which an acoustic transducer is coupled, and a second end of the channel that terminates an acoustic traveling wave launched from the acoustic transducer. The thickness of the channel is linearly tapered from the first end to the second end, so as to maintain a constant acoustic power density. To compensate for the attenuation in acoustic power through the water medium, the waveguide may be heated, to maintain the temperature of the liquid medium (water) within the waveguide channel within a prescribed temperature range over which the acoustic velocity remains substantially constant or undergoes a relatively small variation.Type: GrantFiled: January 22, 1999Date of Patent: March 28, 2000Assignee: Harris CorporationInventors: Robert M. Montgomery, Reeder N. Ward, Mark T. Montgomery, Pat O. Bentley

Patent number: 5801874Abstract: A folded acoustic traveling wave lens arrangement imparts multiple passes of an incident optical beam through the traveling wave lens, and thereby effectively maximize utilization of acoustic power. A lens of optically transmissive bulk material, such as quartz, is disposed in the path of an incident light beam which is spatially scanned by a light beam deflector. The bulk material of the lens element has a reflective layer disposed upon at least one of its surfaces, and is configured such that an incident light beam undergoes multiple passes through the acoustic wavefront propagating through the lens, prior to emerging from the lens. Aberration in the emerging beam due to multiple passes through the bulk material is corrected by a pupil plane correction plate.Type: GrantFiled: June 25, 1996Date of Patent: September 1, 1998Assignee: Harris CorporationInventors: Robert M.
