| An anisotropic spatial acousto-optic modulator for a holographic display system includes a substrate, an anisotropic waveguide that guides light into a single polarization, and a transducer that generates surface acoustic waves that propagate linearly with the guided, polarized light, converting at least some of the polarized light into a leaky mode of orthogonally polarized light.

A holographic video display system includes at least one anisotropic spatial acousto-optic modulator. The pattern of the surface acoustic waves, encoded with holographic information, acts as a diffraction pattern that causes the modulator output to form a wavefront that becomes at least part of a holographic image. The system may have multiple channels in multiple waveguides, wherein each waveguide writes one or more lines of the holographic image. | ||||||

| 10 | Method and system for interference lithography utilizing phase-locked scanning beams | US09711019 | 2000-11-09 | US06882477B1 | 2005-04-19 | Mark Schattenburg; Patrick N. Everett |
| A method and system of interference lithography (also known as interferometric lithography or holographic lithography) which utilizes phase-locked, scanning beams (so-called scanning beam interference lithography, or SBIL). The invention utilizes a high-precision stage that moves a substrate under overlapped and interfering pairs of coherent beams. The overlapped beams interfere, generating fringes, which form a pattern “brush” for subsequent writing of periodic and quasi-periodic patterns on the substrate. The phase of the fringes in the overlapped region is phase-locked to the motion of the precision stage. The invention includes methods for forming, overlapping, and phase-locking interfering pairs of beams on a variety of substrates; methods for measuring and controlling the period, phase, and angular orientation of fringes generated by the overlapping beams; and methods for measuring and controlling the effects of stage mechanical and thermal drift and other disturbances during the writing process. | ||||||

| 12 | Three dimensional display system | US509062 | 1990-04-12 | US5172251A | 1992-12-15 | Stephen A. Benton; Joel S. Kollin |
| A three dimensional display system includes a laser for generating a laser light signal. The signal is expanded and collimated using a traditional lens system and is directed to an acousto-optic modulator wherein it is modulated to generate a three dimensional image such as a holographic image. The modulation signal for the modulator is provided by a data processing system. The data processing system applies signals to the modulator that encode a diffraction pattern. The diffraction pattern is realized by the modulator upon application of the signals and the three dimensional image is produced by the modulated light signals. The image is demagnified by a demagnifier, and subsequently, imaged by a viewing lens. A horizontal scanner continuously multiplexes segments of the holographic image and compensates for the motion of segments across the modulator. A vertical scanner is provided to properly vertically position horizontal lines of the holographic image. | ||||||
