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: The present subject matter includes apparatus and techniques that can be used to reduce losses in systems that perform steering of a light beam. Such steering can be performed in a non-mechanical manner, such as using an electrically-controlled optical structure (e.g., an electro-optical structure). For example, a waveguide can be used to adjust an angle of a light beam (e.g., steer the light beam). The waveguide can include a core, a cladding including an electro-optic material, and electrodes defining an arrangement that, when selectively energized, adjusts an index of refraction of the electro-optic material. In particular, electrode arrangements as described herein can be used to reduce losses, such as losses that would occur due to diffraction.

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.
