英文摘要	A light detection and ranging (LIDAR) transmitter includes a plurality of light emitters that generate a plurality of optical beams. A first lens is positioned in an optical path of the plurality of optical beams at a distance from at least one of the plurality of light emitters that is less than a focal length of the first lens. The first lens converges the plurality of optical beams to a converged optical beam having a beam waist. A second lens is positioned in the optical path of the converged optical beam. The second lens projects the converged optical beam to a target range. The position of the second lens and an 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 at the target range.
