Abstract
A LIDAR system is disclosed. The system has a laser light projection system to simultaneously project at least two laser light beams. The system also has a deflector to project the at least two laser light beams toward a field of view of the LIDAR system. Each of the at least two laser light beams has an energy density below an eye safe level. A total combined energy density of the at least two laser light beams is above an eye safe level. Further, the at least two laser light beams projected from the deflector are separated from one another by an angular spacing ranging from 2.5 mrad to 6 mrad.
