Abstract: A substantially planar waveguide for dynamically controlling the out-of-plane angle at which a light beam exits the waveguide. Generally, liquid crystal materials may be disposed within a waveguide in a cladding proximate or adjacent to a core layer of the waveguide. In one example, the waveguide may contain one or more taper regions such that the light beam exits the waveguide and propagates out-of-the-plane of the waveguide into an out-coupling medium at a propagation angle. In one example, the waveguide may contain one or more electrodes onto which one or more voltages may be applied. The magnitude of the propagation angle may be electronically controlled by altered by controlling or altering the magnitude of the one or more applied voltages.

Abstract: A liquid crystal waveguide (LCW) can include actively controlled incoupling of light into a LCW, such as by using a voltage-controlled electrode to actively vary a property of an LC material arranged to affect the incoupling of light into the LCW. Actively varying light incoupling into the LCW can be used, for example, such as for calibration or compensation or to provide closed-loop feedback such as to stabilize the amount of light into the LCW while accommodating or reducing sensitivity of the LCW to variations in one or more of: input laser light incidence angle, input laser wavelength, LCW or input laser temperature, input laser optical power level, or the like. This can advantageously help improve or maximize light incoupling efficiency, which can improve performance and robustness of the LCW under actual operating conditions. The LCW can be used for, among other things, beamsteering in in-plane and out-of-plane directions.

Abstract: A system and method for providing a dynamic region of interest in a lidar system can include scanning a light beam over a field of view to capture a first lidar image, identifying a first object within the captured first lidar image, selecting a first region of interest within the field of view that contains at least a portion of the identified first object, and capturing a second lidar image, where capturing the second lidar image includes scanning the light beam over the first region of interest at a first spatial sampling resolution, and scanning the light beam over the field of view outside of the first region of interest at a second spatial sampling resolution, wherein the second sampling resolution is less than the first spatial sampling resolution.
