Abstract: A detection apparatus, a control method and control apparatus of the detection apparatus, a lidar system, and a terminal are provided. The detection apparatus includes at least one laser, at least one planar array detector, at least one lens assembly, at least one optical detector, and at least one micro electro mechanical system MEMS micromirror. The lens assembly is configured to focus reflected light of at least one first laser light beam to the planar array detector. The MEMS micromirror is configured to reflect reflected light of at least one second laser light beam to the optical detector.
