    摘要： An electronically steerable optical source comprises a photonic array comprising a plurality of optical antennas arranged along a line, and circuitry configured to control steering of a beam about a first axis substantially perpendicular to the line. A steering range over which the steering of the beam is limited is characterized by first and second vectors at extrema of the steering range. A mounting structure is rotatably attached to a base structure, with the electronically steerable optical source rigidly mounted to the mounting structure. A rotation controller is configured to rotate the mounting structure with respect to the base structure about a second axis by at least 180 degrees, where the electronically steerable optical source is oriented on the mounting structure such that (1) the second axis is not parallel to the line, and (2) the first vector is substantially parallel to the second axis.

    摘要： An optical member having a high reflectivity of electromagnetic waves in a desired direction for use in a metasurface structure. The optical member includes, in the following order: a reflective layer; a liquid crystal layer that includes a liquid crystal compound; and a metasurface structure where a plurality of microstructures are arranged, in which an in-plane refractive index of the liquid crystal layer continuously changes according to a region of the metasurface structure where two or more microstructures arranged adjacent to each other are present.

    摘要： This disclosure describes systems, methods, and apparatus for reducing stray light in a non-mechanical beam steering or light angle alteration application. A non-mechanical beam steering assembly, including polarization-controlling switches and polarization gratings, can be followed by or preceded by a polarization controller, such as a retarder, and a polarizer, such as a linear polarizer. The polarization controller can convert circularly polarization from the non-mechanical beam steering assembly into linear polarization, and then the polarizer can filter for the desired polarization of light thereby reducing stray or unwanted light.

    摘要： An optical scanner includes: a light source; a deflection element including a plurality of pixels arranged one-dimensionally or two-dimensionally; a one-cycle diffraction grating including, among the pixels, continuous N pixels, where N is a natural number of two or more; the one-cycle diffraction grating having a length d in the alignment direction that is smaller than a wavelength λ of the light emitted from the light source; and a phase modulation controller configured to control a phase modulation amount of each of the pixels. Incident light is emitted from the light source obliquely from the reflecting surface at an incident angle θ1. Sin θi+(λ/d)>1 or sin θi−(λ/d)>1 is satisfied.

    摘要： A lens system may include a lens having a first electrode electrode layer, a second electrode layer, and a liquid crystal layer disposed between the first electrode layer and the second electrode layer. The lens may be divided into a plurality of lens segments that are concentrically arranged proceeding from a center to a radially outer periphery of the lens. An optical power of a first lens segment of the plurality of lens segments may be greater than an optical power of a second lens segment of the plurality of lens segments disposed radially outward relative to the first lens segment. Various other devices, systems, and methods are also disclosed.
