  • Patent number: 9074882
    Abstract: A light beam is detected/localized by multisector detector—quad-cell, or 5+ sectors handling plural beams. Preferences: Beams focus to diffraction limit on the detector, which reveals origin direction by null-balance—shifting spots to a central sector junction, and measuring shifts to reach there. One or more MEMS reflectors, and control system with programmed processor(s), sequence the spot toward center: following a normal to an intersector boundary; then along the boundary. One afocal optic amplifies MEMS deflections; another sends beams to imaging optics. After it's known which sector received a spot, and the beam shifts, source direction is reported. The system can respond toward that (or a related) direction. It can illuminate objects, generating beams reflectively. Optics define an FOR in which to search; other optics define an FOV (narrower), for imaging spots onto the detector. The FOR:FOV angular ratio is on order of ten—roughly 180:20°, or 120:10°.

  • Patent number: 9025254
    Abstract: A fiber array for receiving a plurality of light-guiding fibers has a substrate with V grooves for guiding light-guiding fibers. These are fixed inside the V grooves by covers. In order to achieve a better utilization of space, the light-guiding fibers are disposed in two planes. To this end, first fibers in V grooves are fixed on the surface of the substrate in one plane. Second fibers are fixed by V grooves in recesses between the first fibers in a second parallel plane. Here a processing of the substrate may be done without changing clamping or re-clamping of the substrate. Particularly small production tolerances can be achieved by this means.

    Abstract: An optical connector is described. This optical connector spatially segregates optical coupling between an optical fiber and an optical component, which relaxes the associated mechanical-alignment requirements. In particular, the optical connector includes an optical spreader component disposed on a substrate. This optical spreader component is optically coupled to the optical fiber at a first coupling region, and is configured to optically couple to the optical component at a second coupling region that is at a different location on the substrate than the first coupling region. Moreover, the first coupling region and the second coupling region are optically coupled by an optical waveguide.

  • Patent number: 8940238
    Abstract: The present invention is directed to an assembly for use in detecting an analyte in a sample based on thin-film spectral interference. The assembly comprises a waveguide, a monolithic substrate optically coupled to the waveguide, and a thin-film layer directly bonded to the sensing side of the monolithic substrate. The refractive index of the monolithic substrate is higher than the refractive index of the transparent material of the thin-film layer. A spectral interference between the light reflected into the waveguide from a first reflecting surface and a second reflecting surface varies as analyte molecules in a sample bind to the analyte binding molecules coated on the thin-film layer.
