  • Patent number: 9436103
    Abstract: A Wynne-Dyson projection lens for use in an ultraviolet optical lithography system is disclosed, wherein the projection lens is configured to have reduced susceptibility to damage from ultraviolet radiation. The projection lens utilizes lens elements that are made of optical glasses that are resistant to damage from ultraviolet radiation, but that also provide sufficient degrees of freedom to correct aberrations. The glass types used for the lens elements are selected from the group of optical glasses consisting of: fused silica, S-FPL51Y, S-FSL5Y, BSM51Y and BAL15Y.

  • Patent number: 8993307
    Abstract: Apparatus, systems and methods for use in analyzing discrete reactions at ultra high multiplex with reduced optical noise, and increased system flexibility. Apparatus include substrates having integrated optical components that increase multiplex capability by one or more of increasing density of reaction regions, improving transmission of light to or collection of light from discrete reactions regions. Integrated optical components include reflective optical elements which re-direct illumination light and light emitted from the discrete regions to more efficiently collect emitted light. Particularly preferred applications include single molecule reaction analysis, such as polymerase mediated template dependent nucleic acid synthesis and sequence determination.

  • Patent number: 8139141
    Abstract: An RGB-Z sensor is implementable on a single IC chip. A beam splitter such as a hot mirror receives and separates incoming first and second spectral band optical energy from a target object into preferably RGB image components and preferably NIR Z components. The RGB image and Z components are detected by respective RGB and NIR pixel detector array regions, which output respective image data and Z data. The pixel size and array resolutions of these regions need not be equal, and both array regions may be formed on a common IC chip. A display using the image data can be augmented with Z data to help recognize a target object. The resultant structure combines optical efficiency of beam splitting with the simplicity of a single IC chip implementation. A method of using the single chip red, green, blue, distance (RGB-Z) sensor is also disclosed.

  • Patent number: 8134637
    Abstract: An imaging system substantially simultaneously acquires z-depth and brightness data from first sensors, and acquires higher resolution RGB data from second sensors, and fuses data from the first and second sensors to model an RGBZ image whose resolution can be as high as resolution of the second sensors. Time correlation of captured data from first and second sensors is associated with captured image data, which permits arbitrary mapping between the two data sources, ranging from 1:many to many:1. Preferably pixels from each set of sensors that image the same target point are mapped. Many z-depth sensor settings may be used to create a static environmental model. Non-correlative and correlative filtering is carried out, and up-sampling to increase z-resolution occurs, from which a three-dimensional model is constructed using registration and calibration data.

  • Patent number: 6961200
    Abstract: A method and a system for formatting a magnetic tape with identifiable optical servo tracks are disclosed. Multiple optically detectable servo tracks extending lengthwise parallel to the tape transport direction are written simultaneously by directing a spatial beam dot pattern unto the magnetic tape. The beam dot pattern is capable of imparting not only a unique identification, but also other information such as tape longitudinal address, and manufacturer's data to each servo track. The spatial beam dot pattern may also include two arrays of beam dots created via the use of two one-dimensional diffractive optical elements.

  • Publication number: 20030021032
    Abstract: A system to project the image of a virtual input device includes a substrate bearing a diffractive pattern, and a source of collimated light, such as a laser diode. The collimated light interacts with the substrate and the pattern to project a user-viewable image that preferably is the image of a virtual input device. Interaction between a user and the projected image of the virtual input device can then be sensed, and used to input information or otherwise control a companion device, for example a PDA or a cellular telephone.
