Abstract: A mounting process/device for mounting and alignment of micro optical electro-mechanical systems (MOEMS) elements and/or devices. The mounting process/device can be obtained by attaching at least one optical element onto a mounting system, which contains an embedded optical element. The attached optical element(s) are aligned with respect to the embedded optical element.

Abstract: A slider system have been developed to aid in the spacing between read/write heads and the storage medium, and a grating antenna amplifier has been developed to improve illumination spot size and polarization characteristics. The grating antenna can be attached to a grayscale slider to obtain a distance between the illumination spot and antenna that lies in the near field region.

Abstract: An antenna formation device/method has been developed to create variable shaped antennas using predetermined interference patterns to expose and develop a photoresist layer that is etched on a substrate to form the structure corresponding to the desired variable shaped antenna.

Abstract: A mold apparatus is arranged to produce molded optical elements. The apparatus includes a first mold unit for defining mold cavities and flow passageways, and a second mold unit having a patterned surface for sealing against the first unit. The patterned mold surface may be formed with a plurality of optical patterns, and mold pins may be used to complete the mold cavities. The patterned surface may be formed on a flat metal puck. The puck may be replaced by another puck insert so that the apparatus can be used to produce products having different optical characteristics. Other parts of the apparatus may be changed out to produce molded optical elements of various sizes and shapes. A variety of techniques are described for forming micro-refractive, diffractive and/or other patterns in the metal puck surface.

Abstract: An autostereoscopic display and method of displaying multidimensional images involves a first lenticular array preferably of cylindrical lenses positioned between a viewer and a pixel array, and a second lenticular array also preferably of cylindrical lenses positioned between the first lenticular array and the viewer. The pixel array includes several pixel groups that project images through corresponding groups of first lenses within the first lenticular array. A pitch of the lenses within the second lenticular array differs from a pitch of the lenses in the first lens groups within the first lenticular array. The display can be manufactured or retrofit with the first and second lenticular arrays.

Abstract: A display and method of displaying multidimensional images on an autostereoscopic display includes establishing a lenslet array to include a plurality of lens elements. There is an interlacing of a plurality of multiple images on the display with a fanning of the multiple images out into an angular array. The method establishes a plurality of views in a vertical and horizontal direction. A mapping of a plurality of views onto a plurality of pixels makes up the display and a three dimensional image is generated from the fanned out multiple images.

Abstract: A deformable mirror includes a vertical comb actuator having a reflective surface attached thereto. The vertical comb drive includes stationary elements interspersed with moving elements. When a potential difference is provided between these elements, the moving elements are pulled downward, thereby deforming the reflective surface. The vertical comb drive typically includes a plurality of actuators, which are individually electrically addressed. Each actuator may be an array of interspersed elements or a cavity and corresponding tooth. Springs support the moving elements and bias the reflective surface in an original position. The vertical comb drive provides a large stroke and substantially linear voltage-versus-displacement curve throughout the stroke.

Abstract: A micro-electromagnetic device having a three dimensional structure is formed using laser chemical vapor deposition on a conductive surface. Arrays of electromagnetic devices may be formed. Various techniques for facilitating deposition on the conductive surface may be used. A helical antenna for use in the THz region may be formed in accordance with the laser chemical vapor deposition. The antenna is preferably formed on a bolometer.

Abstract: An apparatus for controlling light includes a non-transparent surface for blocking incident light, an array of first lenses for focusing the incident light upon the non-transparent surface, an array of shutters corresponding to the array of first lenses and positioned on the non-transparent surface for controlling passage of the incident light through the non-transparent surface, and an array of second lenses corresponding to the array of shutters for collimating the incident light passing through the shutters. The shutters are separated from the first lenses by a distance equal to a focal distance of the first lenses such that the incident light is focused by the first lenses onto the shutters. As such, the shutters may be opened and closed to control the intensity of the incident light passing therethrough.

Abstract: A system and method for achieving alignment of a mask and substrate focuses a first image (e.g., a reticle) on a first position of a first substrate surface, and determines whether the first position is aligned with a second position on an opposing second substrate surface based on a second image formed based on light from a micro-optical device located on the second surface which collects light from a first image focused thereon. To determine whether the first and second positions are aligned, the first image and the second image are projected on an image plane and compared, the first and second positions being aligned when the first image and the second image are coincident on the image plane. A mask and/or alignment pattern may be formed on the opposing substrate surfaces, and used to generate aligned optics on those surfaces. As such, precise alignment between optics on opposing surfaces of a substrate can be achieved.

Abstract: A method for the replication of diffractive optical elements using audio/video disc manufacturing equipment and processes. The audio/video disc manufacturing process and mold mastering tooling create diffractive optical elements using a mold plate. The diffractive optic design and photomasks are first fabricated then replicated using compact disc industry mold mastering techniques. The surface relief pattern is produced centered in the plate using ion milling or refractive ion etching photolithographic fabrication techniques. Once patterned, the mold master plate is punched into a circular form consistent with standard compact or video disc mold bases--typically eight inches for a compact disc. After molding, each element can be cut out of the disc using blade, shear, waterjet or laser cutting.
