Nonmechanical 3D lidar system

Caption

Researchers developed a new nonmechanical 3D lidar system, which is the size of a business card (seen in front of the system on the left). The system uses dually modulated surface-emitting photonic-crystal lasers (DM-PCSELs) as flash and beam-scanning sources.
