Abstract
A scanner and a method for controlling the scanner for a Lidar system are provided. The method comprises: producing a trigger signal by a positional sensor of the scanner; generating a single drive signal comprising a first component at a first frequency and a second component at a second frequency, the first component and the second component are superposed with a fixed phase relationship with aid of the trigger signal; transmitting the single drive signal to the scanner, and the scanner has resonant responses at the first frequency; and actuating the scanner to move in a first periodic motion at the first frequency about a first axis, and move in a second periodic motion at the second frequency about a second axis.
