Abstract

A multi-wavelength LIDAR system includes a first array of laser emitters that generate a first and second array of optical beams having a first and second wavelength, respectively. A region of free space interleaves the first array of optical beams and the second array of optical beams. An optical receiver receives a portion of light from the first array of optical beams reflected at a target plane and a portion of light from the second array of optical beams reflected at the target plane and generates a first and second plurality of wavelength signals corresponding to the received portion of light from the first and second array of optical beams, respectively. A controller generates a measurement point cloud from the first and second plurality of wavelength signals generated by the optical receiver, where an angular resolution of the measurement point cloud comprises a first angular resolution corresponding to an emitter spacing of the first array of laser emitters and a second angular resolution corresponding to an emitter spacing of the second array of laser emitters.
