摘要： Techniques and devices are disclosed to enhance or increase the viewing angle of liquid crystal display (LCD) device through the use of one or more types of optical films. Such optical films can include arrays of prism structures and/or diffractive elements that redirect light that has passed through an LCD panel. The prism structures and/or diffractive elements can be spaced on an optical film to enable at least a portion of the light travelling through the LCD panel to pass through the optical film without being redirected. Various types of prism structures and/or diffractive elements can be used, and they can be configured on the optical film differently to enable different functionality.

摘要： An assembly structure and method for an integrated laser/detector device with a mirror at an angle to redirect the laser beam to a medium. The mirror is not attached to the circuit board with the laser/detector as in the prior art, but rather is mounted separately in the housing immediately above the circuit board. This allows the circuit board to be moved laterally toward and away from the mirror during assembly to adjust the reflected beam along a first direction so that it contacts the photodetector. A hologram lens is mounted above the mirror, and can be rotated to adjust the reflected beam to hit the photodetector along a second, orthogonal direction. In one embodiment, two laser beams are generated, and two hologram lenses are used to separately adjust the two beams.

摘要： A Fresnel lens of the prior art is split into two Fresnel lenses to allow easier control of the horizontal and vertical viewing angles. In a second embodiment, the Fresnel lens is entirely eliminated. Instead, the diffuser contains elliptical microstructures so that the diffusing cones in orthogonal directions are different, eliminating the need for a Fresnel lens to perform this function. To compensate for the absence of the light collimation provided by the Fresnel lens, a diffuser with spatially varying diffusing angles is used.

摘要： A diffractive unit which can reduce the effect of the nonlinearity of the photo-resist recording material to produce a diffractive device with brilliant color, and describes a method for recording. A cross grating device recorded using the method of this present invention is also described. A diffractive pattern is provided with multiple units, and the period of the diffraction within at least one of the units is spatially varying. It has been discovered that a spatially varying period can offset other effects, such nonlinear characteristics of the material or inter-unit gaps, to reduce the harmonics and improve the color.

摘要： An optical track sensing device, and in particular to an optical sensor for detecting optical tracking information on a moving medium (or stationary medium and moving sensor). The sensing device relies on self-imaging, rather than optics, and obtains a very acceptable detected signal at other than the self imaging plane of the reflection off a moving medium. This provides more flexibility in the placement of the sensor, while still allowing the elimination of optical components by relying on self-imaging instead. In addition, by providing a pattern over the photodetector with a smaller period, higher frequency harmonics are detected, allowing more precise detection of the position of the medium. In one embodiment, the period of the detector pattern is selected to detect the higher harmonics of the grating on the moving medium.
摘要翻译：光学传感器，尤其涉及用于检测移动介质（或固定介质和移动传感器）上的光学跟踪信息的光学传感器。感测装置依赖于自成像而不是光学，并且在移动介质的反射的自成像平面之外获得非常可接受的检测信号。这在传感器的放置方面提供了更多的灵活性，同时仍然允许通过依靠自我成像来消除光学部件。此外，通过在较短周期的光电检测器上提供图案，检测到较高频率的谐波，从而更准确地检测介质的位置。在一个实施例中，选择检测器图案的周期以检测移动介质上的光栅的高次谐波。

摘要： A method for packaging a hybrid device which has a semiconductor laser diode and photodetectors. The laser diode is mounted on a silicon chip (a "silicon submount") containing a photodetector for monitoring the laser power. An array of silicon submounts are mounted on a heat-sink plate which consists of a heat-sink substrate covered with a metal layer. The metal layer is cut in multiple places down to the heat-sink substrate to form multiple conductive strips. The heat-sink plate with the silicon submounts is then covered with a heat-sink cover plate which has identations formed to provide cavities for the silicon submounts. In addition, cavities are provided to allow connections to the conducting metal strips. The combined assembly is then sliced into bars exposing an opening for the laser diode and openings for connections to the conductive strips. The bars are turned on their sides and laminated to a glass substrate to form a front window for the laser diode assembly. The bar is then cut into separate pieces, each having a single laser diode. A photodetector may be mounted on the front of the glass window before or after the bar is cut into pieces.

摘要： A semiconductor laser assembly is provided with a photodetector module and a laser module mounted on orthogonal surfaces of a heatsink. The photodetector module includes a photodetector and two electrically isolated wire bond blocks, each with two surfaces parallel to the orthogonal surfaces of the heatsink. The laser module includes a laser diode bonded and a wire bond region with two surfaces also parallel to the orthogonal surfaces of the heatsink. Both of the wire bond block surfaces of the photodetector modules are thus parallel to the wire bond region surfaces on the laser module, allowing wire connections to be made between parallel surfaces before the heat sink is mounted on a header. One of the surfaces of each of the wire bond blocks and regions is parallel to the pins of a header, allowing attachment of wires from the photodetector module and the laser module to the pins without rotating the header and pins.

The hybrid component contains a laser diode and a detector mounted on the same mechanical structure. This invention allows the placement of all the components substantially along a single optical axis. This arrangement reduces alignment problems and vibrational errors.
