Publication number: 20230289989Abstract: A monocular snapshot four-dimensional imaging method and system are provided. The method includes constructing a numerical simulation model of an imaging system, and optimizing a phase distribution of an entrance pupil plane of the imaging system to determine a point spread function and a lens parameter corresponding to the phase distribution; building the imaging system, calibrating the point spread function, and obtaining a distortion parameter of the imaging system; taking a single shot on a target scene to obtain a single encoded image containing four-dimensional light field information of the target scene, and correcting the single encoded image according to the distortion parameter of the imaging system; and decoding the four-dimensional light field information of the target scene from the single encoded image according to the calibrated point spread function to obtain an intensity image, a polarization contrast image and a depth map of the target scene.Type: ApplicationFiled: May 13, 2022Publication date: September 14, 2023Inventors: Yuanmu YANG, Zicheng SHEN

Patent number: 11355858Abstract: A tunable, optical metasurface can include an optically reflective surface to reflect optical radiation, such as infrared laser light. An array of optical resonant antennas may, for example, extend from or otherwise be positioned on the reflective surface with sub-wavelength spacings of, for example, less than one-half of a wavelength. Voltage-controlled liquid crystal may be positioned in the optical field region of each of the optical resonant antennas. A controller may apply a voltage differential bias pattern to the liquid crystal of optical resonant antennas, that may be arranged in tiled, interleaved, or randomly arranged subsets of optical resonant antennas to attain one-dimensional beam steering, two-dimensional beam steering, and/or spatial beam shaping.Type: GrantFiled: May 25, 2020Date of Patent: June 7, 2022Assignee: Lumotive, LLCInventors: Gleb M. Akselrod, Yuanmu Yang, Patrick Bowen

Publication number: 20200249396Abstract: Systems and methods are described herein for an optical beam-steering device that includes an optical transmitter and/or receiver to transmit and/or receive optical radiation from an optically reflective surface. An array of adjustable plasmonic resonant waveguides is arranged on the surface with inter-element spacings less than an optical operating wavelength. A controller applies a pattern of voltage differentials to the adjustable plasmonic resonant waveguides. The pattern of voltage differentials corresponds to a sub-wavelength reflection phase pattern for reflecting the optical electromagnetic radiation. One embodiment of an adjustable plasmonic resonant waveguide includes first and second metal rails extending from the surface. The metal rails are spaced from one another to form a channel therebetween. An electrically-adjustable dielectric is disposed within the channel.Type: ApplicationFiled: April 20, 2020Publication date: August 6, 2020Inventors: Gleb M. Akselrod, Yuanmu Yang, Patrick Bowen
