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.
