    Abstract: Embodiments of the present disclosure relate to the field of acoustic sensing demodulation with high signal-to-noise ratio, real-time demodulation, and high sensitivity, and in particular, to a parallel sensing and demodulation system for acoustic waves based on dual optical frequency combs. The present disclosure introduces dual optical frequency combs as multi-path parallel input light sources, leveraging features of the dual optical frequency combs including narrow linewidth, stable power, high sensitivity, and the capability of precisely converting signals from the optical domain to the radio frequency domain, so the dual optical frequency combs can be used as multi-channel parallel input light sources for acoustic array detection. Besides, some embodiments of the present disclosure employ three-wavelength adaptive demodulation technology to ensure that the detection of acoustic wave signals at every moment has a high signal-to-noise ratio and improved sensitivity for detecting weak signals.
