Abstract

An autonomous vehicle includes a LIDAR system that includes a waveguide array, a collimator configured to receive a plurality of beams from the waveguide array and output a plurality of collimated beams, and a scanner configured to adjust a direction of the plurality of collimated beams. The vehicle also includes one or more processors configured to determine a range to an object based on a return signal received from reflection or scattering of the plurality of collimated beams by the object and to control operation of at least one of a steering system or the braking system based on the range.
