Abstract: A liquid crystal display panel provides brighter images and better resistance to shock damages and has a plastic frame, four shock-absorbing bars, a base board, a high effective reflector film, a light guide sheet, a prism sheet, a doubled-enhanced film, a liquid crystal glass, an anti-reflector film and a metallic frame. The high effective reflector film with a high efficiency reflective coat and the doubled-enhanced film increase the brightness of the liquid crystal display panel. The anti-reflector film reduces glare from outside light. The shock-absorbing bars isolate the internal components from the frame and provide resistance to shock damage.
Abstract: An ECLD assembly includes a thermally stabilized substrate, a laser device fixedly mounted in relation to the substrate, and a waveguide with a grating region having a grating formed therein. The waveguide is positioned to receive light emitted by the laser device and is attached to a top surface of the substrate. The ECLD's output wavelength is stabilized by one or more of the following: (1) mounting the waveguide so that its outer surface is less than 60 ?m, and preferably less than about 30 ?m from the top surface of the substrate; (2) placing a thermal cover (e.g.

Abstract: A magnetic sector for charged particle beam transport that includes a magnetic field profile that achieves a linear dispersion from a collimated beam of charged particles proportional to their mass-energy-to-charge ratio. In one embodiment, the field profile necessary for the linear dispersion is obtained by the use of shaped, highly permeable poles powered by permanent magnets or electromagnetic coils.

Abstract: A vertical cavity surface emitting laser (VCSEL) device with improved power and beam characteristics. The VCSEL device contains one VCSEL or an array of VCSELs. Each VCSEL has a corresponding integrated microlens, and a heat sink is attached to the device side of the VCSEL device. The heat sink allows improved heat dissipation, and therefore provides improved power characteristics of the VCSEL device output laser beam. The microlens or microlens array allows easier and more compact focussing of the VCSEL device output laser beam. The VCSEL device can be used in a variety of optical systems, and its improved power and focusing characteristics provide a compact, low power, low cost laser system.

Abstract: An optical router switch array includes a plurality of switchable mirror elements having holographic liquid crystal arranged in stack cells. Each of the mirror elements is isolated electrically from the other switchable mirror elements by a plurality of substrates alternative arranged between the switchable mirror elements. Holographic gratings are formed on the holographic liquid crystal by exposure to holography at predetermined incident angles. A single switchable mirror element can also be provided in cases where an array is not required. The switchable mirror elements are polarization insensitive, stable within the operational spectral region, and stable versus temperature. The invention also includes methods for manufacturing a single switchable mirror element and the optical arrray.
Abstract: This invention relates to electromagnetic wave beam paths, formation of the beam, illumination of programmable electromagnetic wave field vector orientation rotating devices (“PEMFVORD”) with an electromagnetic beam, and the technique of projection of the modulated beam. This invention also relates to a unique light path and method of forming the light into a rectangular beam to be used for optical projection systems and, more particularly, in a color and/or black and white liquid crystal device (LCD) projectors that produce high resolution, high brightness and/or three-dimensional images. This invention further relates to a device capable of receiving and displaying two-dimensional and three dimensional images.
Abstract: A lens blocking device is disclosed that includes a frame, a light source mounted on the frame, a carriage having a first end and a second end mounted on the frame for sliding movement between first and second positions, a first mirror mounted on the carriage first end and a lens block holder mounted on the carriage second end and shiftable between third and fourth positions with respect to the carriage, a stage disposed between the light source and the carriage, and including an opening, for supporting an object, an at least partially translucent screen generating a display image operably connected to the support frame, at least one second mirror arranged to reflect an image of an object on the stage from the first mirror, when the carriage is in the first position, onto the screen, and an actuator operably connected to the carriage.

Abstract: The disclosed invention relates to a system and method for aligning reference marks defining the optical center or major reference point on a lens blank with a series of alignment marks, or “fiducials”. The fiducials comprise first and second alignment bars displayed on a display operably associated with a computer, and overlay the reference marks, also displayed on the display. The fiducials may be adjusted to accurately precisely align the lens blank.

Abstract: A wavelength locker comprising a semiconductor or air gap etalon is used to monitor and maintain the output wavelength of a coherent radiation source. Said etalon may be fabricated from a commercially available silicon wafer, with individual regions of the wafer, each functioning as a separate etalon, etched or otherwise processed to produce different thicknesses. Illumination by the coherent radiation source generated transmitted signal intensities that are detected and processed to determine the output wavelength of the coherent radiation source. A wavelength tuner is then used to maintain or vary the output wavelength based on continuous measurements of etalon signal intensity.

Abstract: A configurable wavelength multiplexing device having first, second, and third reflectors. The first reflector has a first state in which it transmits incoming light (having first and second wavelengths) along a first transmitted path and a second state in which it reflects the light along a first reflected path. The second reflector reflects the first wavelength and transmits the second wavelength. The third reflector reflects the first wavelength. The first, second, and third reflectors are oriented so that when the incoming light is transmitted along the first transmitted path, the first wavelength is reflected by the second and third reflectors to travel along second and third reflected paths, the third reflected path intersects the first reflector at an angle such that the first wavelength is transmitted by the first reflector and continues on the first reflected path, and the second wavelength is transmitted by the second reflector.
Abstract: A light beam location adjustment device. The device includes a bulb and a bulb holder and a pivot mount. A reflector is directly attached to the pivot mount. A first pivot mechanism is provided to pivot the pivot mount about a first axis. The first pivot mechanism includes a hinge at the first axis with the pivot mechanism moved by a first adjustment pin. A second pivot mechanism is provided to pivot the pivot mount about a second axis perpendicular to the first axis. The second pivot mechanism includes a pivot connected to the pivot mount which will rotate the pivot mount in response to movement of the pivot.
Abstract: A device and method of manufacturing a single layer multi-state ultra-fast cholesteric liquid crystal includes two optically transparent states with a liquid crystal arranged therebetween, and changing the optical states of the liquid crystal ranging from one state to any combination of broadband reflection, tunable narrow band reflection, light scattering, and transparency in accordance with a voltage applied to the device. A surfactant can be added to reduce the response time and a dichroic dye may be added to include the property of light absorption and reduce the bandwidth. The device can provide any and all of the aforementioned optical states for infrared light, visible light, and ultra-violet light. The desired outputs can be formed according to need, so that predetermined optical states can operate with either no voltage or a particular voltage or voltage range.
