Patent number: 6952513Abstract: An optical apparatus (110) includes a base member (121) with a plurality of grooves (181-187, 191-197), and includes a respective lens (11-17) fixedly mounted in each groove. Optical filters (31-35) are mounted on the support member in predetermined locations. One such lens is fixedly secured to an input optical fiber (21), and the input fiber is used to introduce radiation into the apparatus. Several output optical fibers (22-27) are successively positioned in relation to respective lenses by a fiber positioner (302), which monitors the amount of radiation passing through the fiber being positioned, and then causes a laser (303) to fuse the fiber end to the associated lens in a selected position.Type: GrantFiled: August 6, 2003Date of Patent: October 4, 2005Assignee: Raytheon CompanyInventors: Daniel J. Murphy, Robert B. Chipper, Brent L. Sisney, David H. Rester, James T. Hoggins, James J. Hudgens

Patent number: 6833822Abstract: A vehicle (10) includes an infrared imaging system (11). The system includes an infrared camera (12) positioned in the center of the front grille of the vehicle. The infrared camera includes a window (13) that has a holographic fringe pattern (14) which cooperates with visible light rays (27, 47, 52, 57) to generate an image (29) that is visible at a location spaced from the vehicle. The visible image may, for example, be a trademark or other symbol identifying the manufacturer of the vehicle. Infrared radiation (31) passes through the element and the structure thereof without significant change, and is detected by an infrared detector (33). A visible image corresponding to the infrared radiation is ultimately displayed by a head up display (19) on a portion (16) of the vehicle windshield (17).Type: GrantFiled: December 21, 2000Date of Patent: December 21, 2004Assignee: Raytheon CompanyInventors: Paul Klocek, David H. Rester, Wayne A. Weimer

Patent number: 6768844Abstract: An apparatus includes a support section which supports a further section, an optically transmissive substrate, and a dispersive section, the further section transporting plural signal components at respective frequencies along a path of travel. A plurality of optical fibers have ends fixedly coupled to a surface on the substrate. The dispersive section has a dispersive characteristic which deviates a direction of travel of each signal component by a respective different amount to optically map each signal component between the end portion of a respective fiber and the path of travel in the further section. During assembly, the fiber ends are moved relative to the surface while radiation passing through them is monitored, and then they are fixedly coupled to the surface in a selected position.Type: GrantFiled: March 30, 2001Date of Patent: July 27, 2004Assignee: Raytheon CompanyInventors: Daniel J. Murphy, Robert B. Chipper, Brent L. Sisney, David H. Rester, James T. Hoggins, James J. Hudgens

Patent number: 6456765Abstract: An apparatus for processing optical signals includes a cladding material having therein at least two elongate core regions which serve as respective waveguides. A coupling portion therein includes adjacent and parallel portions of the two waveguides which extend sufficiently closely for a sufficient distance to permit coupling of radiation between these waveguide portions. Structure is provided that respectively permits and frustrates such coupling for respective component signals having respective different wavelengths. The coupling portion may optionally include an externally controlled switching section that can have a selected one of two states in which is respectively transmissive and nontransmissive to radiation.Type: GrantFiled: April 30, 2001Date of Patent: September 24, 2002Assignee: Raytheon CompanyInventors: Paul Klocek, James M.

Patent number: 5652666Abstract: A method of using a display system having a spatial light modulator (14) to display holographic images. The spatial light modulator (14) generates images that represent vertical strips of a hologram. These images are de-magnified by a three-dimensional optics unit (18), in the horizontal direction so as to form image strips. A scanning mirror (45) scans the image strips in a series across an image plane at a rate sufficiently fast that the viewer perceives a composite hologram comprised of these image strips.Type: GrantFiled: October 30, 1995Date of Patent: July 29, 1997Assignee: Texas Instruments IncorporatedInventors: James M. Florence, Chung Chian Wang, David H. Rester

Patent number: 4554558Abstract: A fluid jet print head for producing a plurality of jet drop streams of fluid includes a manifold defining an elongated cavity and an orifice plate defining a plurality of orifices, arranged in at least one row, which communicate with the cavity. A transducer arrangement, including a piezoelectric means, is mounted in the cavity and is spaced from the orifice plate so as to define a fluid reservoir therebetween. The transducer arrangement further includes acoustic isolation material which surrounds the piezoelectric means and supports the piezoelectric means in the cavity. The transducer means, when electrically excited, produces pressure waves of substantially uniform wave front which travel through the fluid in the reservoir toward the orifice plate and cause break up into jet drop streams of fluid flowing through the orifices. The piezoelectric means may include an elongated transducer which defines a plurality of slots extending alternately from opposite sides of the transducer partially therethrough.Type: GrantFiled: July 16, 1984Date of Patent: November 19, 1985Assignee: The Mead CorporationInventors: William R. Beaudet, Mark A. Culpepper, David H. Rester
