Abstract: A beam combiner has a first coating on a first side capable of imparting a first polarization rotation, and a second coating on a second side capable of imparting a second polarization rotation. A first beam impinging on the first side passes through the first and second coatings as a first beam component. Second and third beams impinging on the second side partially reflect off the second coating as a second beam component, and partially transmit through the second coating to reflect off the first coating and exit through the second coating as a third beam component. The first, second and third beam components are disposed at selected positions and have respective selected polarizations as a combined beam spot. The positions and polarization of the beams components result in a projected image having increased allowable brightness and/or having reduced speckle.

Abstract: Briefly, in accordance with one or more embodiments, a scanned beam display, comprises a light source to generate a beam to be scanned and a scanning platform to scan the beam into an exit cone. The scanning platform receives the beam at a selected feed angle, and the scanning platform has a surface structure to redirect the exit cone at an exit angle that is less than the feed angle.

Abstract: An image generation apparatus provides interpolation and distortion correction. The interpolation and distortion correction may be provided in one or two dimensions. Nonlinear image scan trajectories, such as sinusoidal and bi-sinusoidal trajectories are accommodated. Horizontal and vertical scan positions are determined using a linear pixel clock, and displayed pixel intensities are determined using interpolation techniques.

Abstract: Devices are formed on a semiconductor wafer in an interdigitated relationship and are released by deep reactive ion etching. MEMS scanners are formed without a surrounding frame. Mounting pads extend outward from torsion arms. Neighboring MEMS scanners are formed with their mounting pads interdigitated such that a regular polygon cannot be formed around a device without also intersecting a portion of one or more neighboring devices. MEMS scanners may be held in their outlines by a metal layer, by small semiconductor bridges, or a combination.

Abstract: Durable landing pads for a slider air-bearing surface (ABS) are formed of tetrahedral amorphous carbon (t-aC) by filtered cathodic arc deposition. A hard carbon overcoat of the ABS is pierced to anchor the pads. The t-aC is extremely hard and highly stressed, and the pads may be laminated with a stress-relieving material. A rotating angled etching such as ion milling may be performed to undercut the hard carbon overcoat and further anchor the pads. A rotating angled deposition of t-aC may also be performed to round the pad tops, which may be trimmed to smooth corners.
