  • Publication number: 20220059950
    Abstract: An antenna system has a two-dimensional field of view, yet can be implemented on a surface, such as on electronic or photonic integrated circuits. The antenna system includes an array of antennas disposed in a predetermined non-linear pattern and a two-dimensional beamforming network (BFN). The antenna system can be steered/selectively beamformed in two dimensions through beam port selection. The beamforming network is disposed entirely on a single first surface. The beamforming network has a one-dimensional array-side interface disposed on the first surface and a one-dimensional beam-side interface disposed on the first surface. The antennas of the array of antennas are individually communicably coupled to the array-side interface. Segments of the beam-side interface map to respective pixels in the two-dimensional field of view.

  • Publication number: 20210108922
    Abstract: A navigation system includes a star camera having a field of view. The star camera includes a sun shields that selectively block portions of the star camera's field of view, to prevent unwanted light, such as light from the sun or moon, reaching image sensors of the star cameras. Some sun shields include x-y stages or r-? stages to selectively position a light blocker to block the unwanted light. Some sun shields use positionable partially overlapping orthogonally polarized filters to block the unwanted light. Some sun shields use counter-wound spiral windows that are selectively rotated to block the unwanted light. Some sun shields a curved surface that defines a plurality of apertures fitted with individual mechanical or electronic shutters.

  • Patent number: 10935381
    Abstract: Methods and apparatus automatically determine a location, such as of an aircraft or spacecraft, by matching images of terrain below the craft, as captured by a camera, radar, etc. in the craft, with known or predicted terrain landmark data stored in an electronic data store. A star tracker measures attitude of the camera. An additional navigation aiding sensor provides additional navigational data. Optionally, a rangefinder measures altitude of the camera above the terrain. A navigation filter uses the attitude, the additional navigational data, and optionally the altitude, to resolve attitude, and optionally altitude, ambiguities and thereby avoid location solution errors common in prior art terrain matching navigation systems.

  • Patent number: 10901190
    Abstract: A digital camera optically couples a monocentric lens to image sensor arrays, without optical fibers, yet shields the image sensor arrays from stray light. In some digital cameras, baffles are disposed between an outer surface of a monocentric lens and each image sensor array to shield the image sensor arrays from stray light. In other such digital cameras, an opaque mask defines a set of apertures, one aperture per image sensor array, to limit the amount of stray light. Some digital cameras include both masks and baffles.

  • Patent number: 10837755
    Abstract: A multi-beam optical phased array on a single planar waveguide layer or a small number of planar waveguide layers enables building an optical sensor that performs much like a significantly larger telescope. Imaging systems use planar waveguides created using micro-lithographic techniques. These imagers are variants of “phased arrays,” common and familiar from microwave radar applications. However, there are significant differences when these same concepts are applied to visible and infrared light.

  • Patent number: 10739520
    Abstract: An all-solid state optical transmit/receive terminal includes binary optical switches to steer an optical beam, without mechanical components, phased array of emitters/collectors or large number of phase shifters. A lens optically couples a surface array of emitters/collectors to free space, giving each emitter/collector a respective direction in free space. The emitters/collectors are also coupled, via an “H-tree” or other branched optical waveguide network, to a common input/output port, and from there to a receiver and/or transmitter. The binary optical switches are disposed at optical junctions of the optical waveguide network. ON switches pass an optical signal through the optical waveguide network, between the common input/output port and one or more selected emitter/collectors, thereby selecting a free space direction(s). Only a relatively small subset of the binary optical switches needs to be ON, therefore powered, simultaneously at any given time.

  • Patent number: 10684420
    Abstract: A steerable optical transmit and receive terminal includes a MEMS-based N×1 optical switch network. Each optical switch in the optical switch network uses an electrostatic MEMS structure to selectively position a translatable optical grating close to or far from an optical waveguide. In the close (“ON”) position, light couples between the translatable optical grating and the optical waveguide, whereas in the far (“OFF”) position, no appreciable light couples between the translatable optical grating and the optical waveguide. The translatable optical grating is disposed at or near a surface of the optical switch network. Thus, the translatable optical grating emits light into, or receives light from, free space. The steerable optical transmit and receive terminal also includes a lens and can steer a free space optical beam in a direction determined by which port of the N×1 optical switch network is ON.

  • Patent number: 10641859
    Abstract: A star tracker includes a lens slice, a pixelated image sensor, an ephemeral database and a processor configured to estimate attitude, orientation and/or location of the star tracker based on an image of one or more celestial objects projected by the lens slice onto the pixelated image sensor. The lens slice is smaller and lighter than an optically comparable conventional lens, thereby making the star tracker less voluminous and less massive than conventional star trackers. A lens slice is elongated along one axis. Optical performance along the elongation axis is comparable to that of a conventional circular lens of equal diameter. Although optical performance along a width axis, perpendicular to the elongation axis, of a lens slice can be significantly worse than that of a conventional lens, use of two orthogonal lens slices provides adequate optical performance in both axes, and still saves volume and mass over a conventional lens.

  • Patent number: 10636918
    Abstract: A single photon detection circuit is described that includes a germanium photodiode that is configured with zero voltage bias to avoid dark current output when no photon input is present and also is configured to respond to a single photon input by generating a photovoltaic output voltage. A single electron bipolar avalanche transistor (SEBAT) has a base emitter junction connected in parallel with the germanium photodiode and is configured so that the photovoltaic output voltage triggers an avalanche collector current output.

  • Patent number: 10534063
    Abstract: A zero-optical-path-length-difference optical phased array built with essentially planar photonic devices determines a direction to an incoherent optical source, such as a star. The phased array can replace a 3-dimensional star tracker with a nearly 2-dimensional system that is smaller and lighter. The zero-optical-path-length-difference phased array can be optically connected to an interferometer. Driven by a light source, the zero-optical-path-length-difference phased array can be used as an optical projector.

  • Patent number: 10511782
    Abstract: A configurable optical baffling includes an outer housing positioned above a fixed platform and has an outer opening. An inner housing is layered below the outer housing and above the fixed platform and has inner openings and inner shaded sections. The outer opening includes an elongated sensing boresight having a longitudinal boresight axis and opposing ends. An outer boresight opening end is open to the light from the scene, and a reflecting end has a flat fold mirror that is configured to reflect light from the outer boresight opening in towards the inner housing so that the optical baffling is configured to receive light from the scene solely from a single look direction along the boresight axis, the single look direction being changeable by rotation of the outer housing.
