Abstract: This application provides an optical device, including an emitting assembly configured to emit an outgoing light signal, a beam splitting assembly configured to pass the outgoing light signal from the emitting assembly to a detection region, receive a reflected light signal from the detection region, and modify a transmission direction of the reflected light signal, a receiving assembly configured to receive the reflected light signal from the beam splitting assembly after the direction modification and generate an electrical signal in response to the reflected light signal. Also disclosed is a method of adjusting an optical device as described herein.

Abstract: Embodiments of the present disclosure provide an emission module and a mounting and adjustment method of the same, a LiDAR and a smart sensing device. An emission module includes an emission apparatus and a collimating element provided sequentially along an outgoing laser, where the emission apparatus is configured to generate the outgoing laser, and the collimating element is configured to collimate the outgoing laser generated by the emission apparatus and emit the outgoing laser; and the collimating element includes a fast-axis collimating element and a slow-axis collimating element provided sequentially along the outgoing laser, the fast-axis collimating element is configured to receive the outgoing laser generated by the emission apparatus and collimate the outgoing laser in a fast-axis direction, and the slow-axis collimating element is configured to receive the outgoing laser collimated in the fast-axis direction, collimate the outgoing laser in the slow-axis direction and emit the outgoing laser.

Abstract: An apparatus in the field of optics technology, can include a reflector, a reflector substrate, and an extinction component. The reflector can be mounted on the reflector substrate. The extinction component can be arranged on a front surface of the reflector substrate. The reflector can be configured to reflect incident light signals. The extinction component can be configured to reduce the scattered light produced by the incident light signal on the reflector substrate. An optical scanning device (for example, lidar) having such features may greatly reduce the scattered light inside the lidar, reduce the detection blind area caused by the stray light, and greatly improve the receiving and detecting capabilities of the lidar.
