Modulation method, apparatus, and system for imaging scanning signal synchronization

A modulation system for imaging scanning signal synchronization, comprising:

• a signal generator;
• an industrial camera, a laser emitter, and a galvanometer that are respectively in communication connection with the signal generator;
• a sensor in communication connection with the galvanometer;
• and
• a graphics processor in communication connection with the signal generator and the sensor respectively,
• wherein the signal generator is configured to transmit control signals to the industrial camera, the laser emitter, and the galvanometer, and simultaneously transmit the control signals to the graphics processor, the control signals comprise a galvanometer driving signal, a laser scanning signal, and a camera exposure signal;
• the sensor is configured to collect an actual signal waveform capable of reflecting an actual state of the galvanometer, output a noise-reduced waveform and transmit the noise-reduced waveform to the graphics processor;
• and
• the graphics processor is configured to perform detection comparison on the actual signal waveform and the galvanometer driving signal for the galvanometer in the control signals, and transmit a result of the detection comparison to the signal generator to adjust the laser scanning signal and the camera exposure signal.
