Abstract
A multi-wavelength array lidar system and a method of designing an array lidar system include arranging a plurality of lasers in an array to transmit a respective plurality of beams, arranging a lens to disperse the plurality of beams at a respective plurality of angles, and arranging a band pass filter to filter a plurality of reflections received at a respective plurality of incident angles resulting from the plurality of beams transmitted by the plurality of lasers at a respective plurality of transmit angles. Selecting a transmit wavelength of each of the plurality of beams is based on the respective plurality of transmit angles to ensure that a receive wavelength of each of the plurality of reflections is within a narrower range than a range of the transmit wavelengths.
