摘要： A dual-wavelength phase range finder for improving measurement of vision capture is provided. A frequency synthesizing device generates a high-frequency modulation signal, and the high-frequency modulation signal forms an outer optical path and an inner optical path after passing through a laser processing device. A processing device controls a laser aiming device to emit a visible light signal. A filtering device allows a first reflecting light signal and a second invisible light signal to pass through, and blocks a second reflecting light signal. The processing device further controls a receiver to process the first reflecting light signal and a reference signal to obtain a first low-frequency signal, and controls the receiver to perform a photoelectric frequency mixing process on the second invisible light signal and the reference signal to obtain a second low-frequency signal. The processing device determines a distance based on the first and second low-frequency signals.
