Abstract: A detection control method and an apparatus are described that are used for target detection, and may be applied to the fields such as intelligent driving, intelligent transportation, surveying and mapping, and intelligent manufacturing. A control apparatus controls a laser emitting unit and a laser receiving unit to perform two phases of laser detection. A first phase of laser detection is used to determine a time location, and a second phase of laser detection is used for target detection in a time window including a first time location. In one aspect, in the second phase of detection process, the control apparatus controls a laser detection unit to receive an echo signal in a first time window. A time for receiving the echo signal is shortened, thus permitting an amount of data in the detection process to be reduced.

Abstract: A detection device includes a transmitting component, configured to transmit a laser beam; a collimating and shaping component, configured to process the laser beam as a collimated linear laser beam; a scanning rotating mirror component, including at least one reflection surface, configured to reflect the linear laser beam; a receiving component, configured to receive a target echo, and convert the target echo from an optical signal into an electrical signal corresponding to the target echo, where the target echo includes a reflected signal of the linear laser beam.

Abstract: A detection apparatus includes a scanning system, the scanning system includes a micro reflector array, and the micro reflector array includes M micro reflectors. The detection apparatus further includes P transceiver modules. An optical signal sent by the P transceiver modules is reflected by the M micro reflectors, and/or the P transceiver modules receive an optical signal reflected by the M micro reflectors. The P transceiver modules do not need to receive and send signals using one micro reflector, but may receive and send signals by using the M micro reflectors.

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.
