Abstract

A LIDAR system is disclosed. The system may include a laser light projection system that may simultaneously provide at least two laser light beams. The system may also include an optical system, including one or more deflectors to project the at least two laser light beams toward a field of view of the LIDAR system. Each of the laser light beams may have an energy density below an eye safe level. However, a total combined energy density of the laser light beams may exceed an eye safe level. The laser light beams may be projected from the deflector are spaced apart from one another by an angular spacing ranging from 2.5 mrad to 6 mrad.
