摘要： An optical phased array including a wafer, optical waveguides, a root optical waveguide, the root optical waveguide being optically connected at one end to one optical waveguide, another end of the root optical waveguide constituting an optical port, optical couplers disposed in an array and located on the wafer, the optical waveguides optically connecting the optical couplers to the optical port via respective optical paths, one optical path per optical coupler, configurable optical delay lines; each configurable optical delay line being disposed in one respective optical path from the respective optical paths; the configurable optical delay lines being configured such that the optical couplers emit a non-planar phase front near field radiation pattern from light received from a light source coupled to the optical port.

摘要： An optical device is described for a wide field of view optical system. A device housing has an optical opening into an enclosed interior volume. A multi-element lens is molded across the optical opening and defined by: a. a field of view representing a volume of space from which light is collected, b. a plurality of optical paths through the lens defining one or more focal planes within the interior volume, and c. a boresight axis perpendicular to each of the one or more focal planes. Optical sensors are arranged on the one or more focal planes and configured for sensing light collected through the lens from the field of view. The device forms a single environmentally hardened package configured to absorb impulse shocks without disturbing the boresight axis or the plurality of optical paths.

摘要： A device and method for selectively illuminating and designating multiple targets in the air or on the ground simultaneously. The device comprises a light source, a switching array and a ball lens. Light from the light source is routed through the switching array, which can addressably output multiple light beams simultaneously. The light beams from the switching array illuminate the backside of a low F-number ball lens. The ball lens creates highly collimated output beams independently (and simultaneously) from any of the output source points of the switching array. These output beams can be used to simultaneously designate multiple targets. When the target illuminating device includes an optional detector array, light scattered from targets can be refracted by the balls lens to impinge on the detector array. Signals from the detector array representing the received light beams can be used for target imaging.

摘要： A chip scale star tracker that couples starlight into a lightguide such that the angle of incidence partially determines the mode of propagation of the starlight in the lightguide. A baffle system integrated with the lightguide prevents propagation of light incident from a predetermined range of angles.

摘要： A chip scale star tracker that captures plane-wave starlight propagating in free space with a wafer-thin angle-sensitive broadband filter-aperture, and directs the light into a waveguide structure for readout. Angular information about the star source is determined from characteristics of the starlight propagating in the waveguide. Certain examples include internal propagation-constant-based baffling to elimination stray light from extreme angles.
