  • Publication number: 20060176362
    Abstract: An optical system is provided for projecting an image having x and y axes onto print material. The system includes an SLM device spaced from the print material, the SLM device having a plurality of pixels operable to project pixels of the image onto the print material and positioned such that the individual pixels of the projected image are oriented at substantially 45 degrees relative to the x and y axes of the image. The system further includes a modulating device operable to create relative movement between the print material and the projected image to provide increased image resolution and dithering.

  • Publication number: 20060176323
    Abstract: An optical system for projecting an image having x and y axes onto a image plane is provided. The system includes an SLM device spaced from the image plane, the SLM device having a plurality of pixels operable to project pixels of the image onto the image plane and positioned such that the individual pixels of the projected image are oriented at substantially 45 degrees relative to the x and y axes of the image. The system further includes an optic element disposed between the SLM device and the image plane and a linear displacement device operatively connected to and operable to selectively displace at least one of the SLM device and the optic element. A method for projecting an image onto a image plane is also provided.

  • Patent number: 6905259
    Abstract: Disclosed is a mounting system and method in which symmetrical springs are used about a collar in a gimbal system to capture an assembly of a ball and an optical or other type of component. Once captured within the mounting system, the ball/component assembly can pivot until an optimal alignment is reached. Once the optimal alignment is reached, the ball/component assembly is fixed using laser welding.

  • Publication number: 20050095009
    Abstract: Described embodiments provide for an optical communications assembly or other optical assembly in which the post-dispersion optical signals are controlled in dispersive and non-dispersive directions. In one embodiment, the assembly includes an optical signal collimator configured to emit an optical signal based on an input communication signal. In addition, the assembly includes a dispersive device that receives the optical signal and disperses multiple wavelength channels of the optical signal in a dispersive direction. The assembly further includes a first light-directing device configured to control the dispersion of the multiple wavelength channels in the non-dispersive direction. A second light-directing device is provided to control dispersion in the dispersive direction.

  • Publication number: 20040184717
    Abstract: Disclosed herein is an improved optical interface system for a DMD array. One embodiment of the disclosed invention comprises an optical beam module that has an integral optical waveguide with waveguide ports at each end. The optical waveguide receives an input light beam through a first waveguide port. The input light beam passes through the waveguide and is emitted from the second waveguide port, where it is reflected by the reflective surface. The reflective surface can be integral to the optical beam module, or it can be mounted onto the module. After being reflected by the reflective surface, the input light beam can be directed onto the surface of a DMD array, where some or all of the input light beam can be selectively reflected in a particular direction. The reflective surface may also comprise a diffractive grating, which reflects the various wavelengths components of the input light beam at varying angles, thereby enabling wavelength selective switching.

  • Publication number: 20040151496
    Abstract: A dynamic gain equalizer-monitor (DGEM) includes a light modulator operable to modulate one or more component wavelengths of an input optical signal. The DGEM also includes a grating operable to receive one or more modulated component wavelengths from the light modulator. The grating is also operable to combine a first portion of each of the one or more modulated component wavelengths and transmit that first portion into an output optical signal. The DGEM may also include a detector array operable to receive, from the grating, a second portion of modulated component wavelengths that are separated from the first portion by the grating. The detector array is operable to generate an electrical signal proportional to an optical characteristic associated with each of the modulated component wavelengths of the second portion.

  • Patent number: 5686681
    Abstract: An extractor (30) for removing string clamping plates (26) from Floyd Rose tremolos (20) has a tongue (36) with a pin (38) which can engage hole (27) in plate (26) so that threaded element (42) when rotated will engage saddle surface (23) and apply upward force on tongue (36) and pin (38) and thus pull plate (26) into cylindrical extension (46) during removal of the string clamping plate.

  • Patent number: 5518674
    Abstract: A method of forming an interconnect including the steps of providing a processing substrate, adhering a first electrically insulating layer to the substrate, forming an electrically conductive pattern on the first electrically insulating layer, forming a second electrically insulating layer adhered to the first electrically insulating layer with the electrically conductive pattern between the first and second electrically insulating layers, forming connections to the pattern and then removing the adhered first and second electrically insulating layers and the electrically conductive pattern from the substrate to provide a freestanding film.

  • Patent number: 5291019
    Abstract: An improved interconnect structure for electrically connecting an infrared detector to external circuitry wherein thin film metal conductors are deposited on a thin, insulating tape. One end of the structure terminates at the detector at about 77.degree. Kelvin, the other end terminating at external electronics at about 300.degree. Kelvin. Due to the small cross section of the conductor, heat leak to the detector is minimized. In addition, the carrier film is only 15 microns thick, thus minimizing outgassing material. The use of epoxies is eliminated. The structure can be fabricated in a variety of configurations using standard semiconductor equipment.
