    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.

    Abstract: A detection system, a terminal device, and a detection control method are provided, to resolve a problem of low detection accuracy of a detection system in the conventional technology, and are used in fields such as autonomous driving, intelligent driving, assisted driving, or networked vehicles. The detection system includes a transmit module, a receive module, a first scanning module, and a second scanning module. An included angle between a first normal vector of a first reflective surface of the first scanning module and a second normal vector of a second reflective surface of the second scanning module is a first angle greater than 0 degrees. The first reflective surface and the second reflective surface are adjacent reflective surfaces. An included angle between an optical axis of the transmit module and an optical axis of the receive module is a second angle greater than 0 degrees.

    Abstract: The present disclosure relates to light detection and ranging (LiDAR) systems, such as LiDAR sensors detecting objects with various reflectivities at various distances. An optical detection system includes a transmitter for emitting at least one beam of optical radiation, a receiver including an imaging processor and an anamorph prism system, and at least one scanner for guiding the at least one beam along a scan direction across a target scene and/or guiding a reflected optical radiation of the at least one beam from the target scene to the receiver. The anamorph prism system is configured to produce a processed beam by compressing the reflected optical radiation in a predefined direction by a predefined factor. The imaging processor includes a two-dimensional detector and is configured to generate an image based on the processed beam on the two-dimensional detector, the image having an aspect ratio that is based on the predefined factor.

    Abstract: A laser includes a light source, a scanning unit, a receiving lens, a homogenizing unit, a light detection unit, and a processing unit. The light source is configured to output a laser beam. The scanning unit is configured to guide the laser beam to a specified region. The receiving lens is configured to converge an echo light signal formed through reflection of the laser beam. The homogenizing unit is configured to uniformly emit the converged echo light signal onto a photosensitive pixel of the light detection unit, which includes a plurality of photosensitive cells. The plurality of photosensitive cells are used to convert the received echo light signal into an echo electrical signal and are controlled by a plurality of gating circuits. The processing unit is configured to analyze an echo electrical signal output by the plurality of photosensitive cells in a gating period.
