Abstract
A LIDAR illuminator includes a laser array comprising a plurality of laser sources configured to generate an optical beam when energized and a laser driver assembly. A controller is configured to instruct the laser driver assembly to energize the plurality of laser sources based on a firing pattern rule that ensures that optical energy in a particular aperture that is positioned at a particular distance from outputs of the plurality of sources is less than a maximum permissible exposure limit corresponding to a wavelength of emission of the optical beams generated by the plurality of laser sources.
