Abstract

An apparatus is provided that includes a LIDAR system with a waveguide array arranged in a first plane. The waveguide array is configured to generate a plurality of beams where each beam is transmitted from a respective waveguide in the array. The apparatus also includes a collimator configured to shape the plurality of beams into a fan of collimated beams having an angular spread in the first plane. Additionally, the apparatus includes a polygon scanner configured to adjust a direction of the fan in a second plane that is different than the first plane. A method is also provided employing the apparatus.
