Abstract: A scene projector including an array of light emitting pixels, a tunable filter element, and a spatial light modulator. The tunable filter element is optically coupled to the array of light emitting pixels such that light emitted from the array of light emitting pixels is passed through the tunable filter element as filtered light. The spatial light modulator is optically coupled to the array of light emitting pixels and is configured to generate transmitted light by interacting with the filtered light to control at least one of an amplitude, a phase, and a polarization of the filtered light.

Abstract: A device includes a photonic integrated circuit (PIC), which includes an optical phased array. The optical phased array includes multiple array elements, where each array element includes (i) an antenna element configured to transmit or receive optical signals and (ii) a phase modulator configured to modulate the optical signals transmitted or received by the antenna element. The PIC also includes at least one of (i) a source laser configured to generate optical energy, where the antenna elements are configured to transmit the optical signals based on the optical energy, and (ii) a receiver configured to receive and process the optical signals received by the antenna elements.

Abstract: Method and apparatus for measuring a Doppler effect of a scattered light include: projecting an ultra violet (UV) light towards a target by a light emitter; receiving the UV light scatter from the target from the emitted UV light reflected from the target by a light receiver; measuring the frequency shift of the UV light scatter with respect to the emitted UV light to obtain distribution of line of sight velocity of macroscopic matters of the target corresponds to a Doppler shift; processing the distribution of the line of sight velocity to determine the Doppler effect of the UV light scatter; and separating the wind line of sight velocity as the centroid shift of the microscopic Doppler shift probability distribution.

Abstract: An apparatus includes a photonic integrated circuit having an optical phased array, where the optical phased array includes multiple unit cells. Each unit cell includes an antenna element configured to transmit or receive optical signals having a linear polarization of light. Each unit cell also includes a modulator configured to phase-shift the optical signals transmitted or received by the antenna element. Each unit cell further includes a quarter waveplate configured to convert between the linear polarization of light and a circular polarization of light.
