Abstract
A solid-state LIDAR transmitter includes a laser array comprising first and second laser pixels that each generate first and second sub-aperture beams. A first microlens focuses first and second sub-aperture beams generated by the first laser pixel and focuses first and second sub-aperture beams generated by the second laser pixel. A second microlens directs the first and second sub-aperture beams generated by the first pixel such that they overlap at a plane. A lens projects the first sub-aperture beam generated by the first laser pixel and the first sub-aperture beam generated by the second laser pixel with a different angle in the far field in order to achieve a desired spatial resolution of the LIDAR system.
