Abstract: An optical emitting device and an optical sensor are provided. The optical emitting device includes a body, a light source, and a first light-blocking structure. The body has an emitting cavity extending in a first preset direction. The emitting cavity has an incident light port and an emergent light port that are arranged in the first preset direction. An inner wall of the emitting cavity has a first inner wall portion and a second inner wall portion. The first inner wall portion and the second inner wall portion are oppositely arranged. The light source and the body are arranged in the first preset direction. The first light-blocking structure is arranged in the first inner wall portion of the emitting cavity. A light-transmitting channel is arranged between the first light-blocking structure and the second inner wall portion. The first light-blocking structure includes a plurality of first light-blocking sheets.

Abstract: This application relates to a galvanometer-based laser synchronization controlling method, calibration method and apparatus, and a LiDAR. The galvanometer-based laser synchronization controlling method includes obtaining a fast-axis feedback signal when a galvanometer scans; obtaining a first phase difference between a fast-axis drive signal and the fast-axis feedback signal and obtaining a second phase difference between an emission period of a laser beam and the fast-axis drive signal; and setting a phase for the fast-axis drive signal based on the first phase difference and the second phase difference.
