Abstract: The present application discloses a LiDAR, which includes a base including a bearing surface, an adjusting structure located on the bearing surface, and a laser transceiving module including a plurality of laser transceiving devices. A galvanometer module of the LiDAR is fixed on the bearing surface. Each laser transceiving device is fixed on the adjusting structure, respectively. Each laser transceiving device is able to generate an outgoing laser emitted to the galvanometer module, respectively. The adjusting structure is configured so that each of the laser transceiving devices has a corresponding distance from the bearing surface, and therefore, the outgoing lasers generated by each of the laser transceiving devices form a preset laser detection field of view outside the LiDAR.

Abstract: The present application discloses a laser emitting circuit and a LiDAR. In a one-driving-multiple emitting circuit, in an energy storage stage, a power supply stores energy for an energy storage element of the energy storage circuit, and a laser diode does not emit light. In an energy transfer stage, by setting a floating-ground diode D0, an energy charging current passes through an energy storage capacitor C2, the floating-ground diode D0 and the ground to form a loop. In an energy release stage, when the energy release switch element is in an off state, the energy release circuit where the energy release switch element is located is not the lowest impedance loop. A laser diode in the energy release circuit where the energy release switch element is located does not emit light.

Abstract: Embodiments of a laser transceiving module and a LiDAR are disclosed. The laser transceiving module includes a housing; an emitting module configured to emit emergent laser signals; a laser splitting module; and a receiving module. The emergent laser signals emit, through the laser splitting module, outwards and are reflected by a target object in a detection region to return reflected laser signals. The laser splitting module is configured to deflect the reflected laser signals. The receiving module is configured to receive the deflected reflected laser signals. The emitting module, the laser splitting module, and the receiving module are fixed at the housing. An extinction structure is arranged between the emitting module and the laser splitting module and is configured to prevent the emergent laser signals that are reflected by the laser splitting module from emitting to the receiving module.
