1. An optical sensing method for an optical sensing system, the method comprising:
determining environment information of an environment surrounding the optical sensing system, wherein the environment information indicates a current detection distance of the optical sensing system;
determining a divergence amount for outgoing optical signals emitted by an optical source of the optical sensing system, based on the current detection distance, wherein the divergence amount is a target divergence amount determined to be smaller at a larger current detection distance to reduce a beam spot size of returning optical signals;
dynamically adjusting the outgoing optical signals to the target divergence amount; and
emitting the outgoing optical signals to the environment.
