VCSEL LIDAR VCSEL ARRAY LIDAR TRANSMITTER WITH SMALL ANGULAR DIVERGENCE

摘要

A light detection and ranging (LIDAR) transmitter includes a plurality of light emitters that generate a plurality of light beams. The first lens is positioned in the optical path of the plurality of light beams at a distance from at least one of the plurality of light emitters less than a focal length of the first lens. The first lens converges the plurality of light beams into a converged light beam having a beam waist. A second lens is positioned in the light path of the converged light beam. The second lens projects the converged light beam into the target range. The position of the second lens and the emission width of at least one of the plurality of light emitters are configured to provide a desired field-of-view of the LIDAR transmitter in the target range.
