Abstract: Embodiments of this application disclose a LiDAR, an autonomous driving system, and a mobile device. The LiDAR includes an emitter, a receiver, a beam splitter, a transceiver lens, a scanner, and an extinction module. Along a transmission path of detection light, the beam splitter is downstream of the emitter, the transceiver lens is downstream of the beam splitter, and the scanner is downstream of the transceiver lens. Along a transmission path of echo light, the beam splitter is upstream of the receiver, the transceiver lens is upstream of the beam splitter, and the scanner is upstream of the transceiver lens, the detection light and the echo light share the transceiver lens. The extinction module includes a first extinctor positioned at an outgoing end of the emitter, a second extinctor positioned at a receiving end of the receiver, and a third extinctor positioned between the transceiver lens and the scanner.

Abstract: The present application discloses an optical receiving device, including: a receiving sensor; an optical assembly arranged on a side where a photosensitive surface of the receiving sensor is located. The optical assembly includes a first prism having a first end surface, a second end surface, and a plurality of sides connected between the first end surface and the second end surface. The plurality of sides include a first side and a second side. At least a portion of laser signals reflected by a detecting target is refracted by the first side and enter the first prism. At least a portion of laser signals refracted by the first side is refracted by the second side and emitted from the first prism to reach the receiving sensor.

Abstract: The present application discloses an optical receiving device and an optical sensing device. The optical receiving device includes a lens assembly, a reflecting member, and a photosensitive member. The lens assembly includes at least one lens. The reflecting member is located on a transmission path of light passing through the lens assembly. The reflecting member has a reflecting surface. The reflecting surface is configured to reflect the light passing through the lens assembly. The photosensitive member has a photosensitive surface. The photosensitive surface is configured to receive light reflected by the reflecting surface. After passing through the lens assembly, a detecting echo light beam reflected back from a target object is reflected by the reflecting surface of the reflecting member, so that the light is transmitted to the photosensitive surface of the photosensitive member intensively.
