Abstract
The present disclosure provides a modulation method, apparatus, and system for imaging scanning signal synchronization. The method includes: transmitting control signals, wherein the control signals include a galvanometer driving signal, a laser scanning signal, and a camera exposure signal, the galvanometer driving signal and the camera exposure signal have a same period, and the laser scanning signal enables laser to be emitted for N times within time for enabling positive oscillation of a galvanometer in one period of the galvanometer driving signal; measuring an actual signal waveform of the galvanometer, and obtaining a noise-reduced waveform by filtering and de-noising the actual signal waveform; performing a waveform comparison detection on the noise-reduced waveform and a corresponding control waveform for the galvanometer driving signal to obtain a waveform deviation; and adjusting the control signals based on the waveform deviation and transmitting the adjusted control signals.
