Type: article
Abstract: Laser remote sensing based on wavefront sensors shows great potential for detecting minute vibrations. However, due to their high detection sensitivity, wavefront sensors are highly susceptible to interference from environmental noise and instrument-induced noise, which significantly compromises the quality of the acquired vibration signals and the accuracy of the detection. In this study, over 60,000 vibration signal data samples were collected under various amplitude and frequency conditions using a laser remote sensing seismic wave detection system. By applying a physics-aware dual-channel decoupled network (PRISM) to perform noise reduction on the vibration signals, we achieved improvements in signal quality under multiple real-world noise environments. The average signal-to-noise ratio improved by 12.16 dB, and the signal distortion ratio improved by 6.35 dB, successfully preserving faint vibration signals within the noise.
