Claim 7:
8. A lidar system comprising:
a metasurface lens configured to focus light pulses received by the lidar system, wherein the metasurface lens comprises a first wafer and a plurality of metasurface structures integrated on the first wafer, and wherein each of the plurality of metasurface structures include at least one dimension that is less than a wavelength of the light pulses; and
a plurality of photodiodes, wherein the metasurface lens is reflective, the plurality of photodiodes are arranged at a first side of the first wafer and the plurality of structures are arranged at a second side of the first wafer opposite the first side, and wherein the plurality of structures are configured to receive the light pulses through the first wafer and reflect the light pulses back through the first wafer to the plurality of photodiodes.
