Claim 17:
18. A light detection and ranging (LIDAR) system comprising:
an optical system, wherein the optical system comprises:
a substrate, wherein the substrate is optically transparent;
at least one optical waveguide disposed on the substrate;
a plurality of mirror surfaces coupled to the at least one optical waveguide, the plurality of mirror surfaces including at least a first mirror surface and a second mirror surface; and
a lens, wherein the lens is configured to couple light into the at least one optical waveguide, wherein the at least one optical waveguide is configured to guide the light to each of the plurality of mirror surfaces, wherein a first portion of the guided light interacts with the first mirror surface so as to direct first reflected light out of the at least one optical waveguide and through the substrate, wherein a second portion of the guided light interacts with the second mirror surface so as to direct second reflected light out of the at least one optical waveguide and through the substrate,
wherein the lidar system is configured to obtain information about one or more objects in a given environment.
