Title: Remote 3D Laser System for Measuring Object Vibrations with Parasitic Vibration Correction
Keywords: interference wedge system, laser-based sensing, parasitic vibration correction, remote 3D vibration registration, water mirror

Abstract: laser-based system that enables remote detection of vibrations and displacements in structures (transport bridges, rock masses, buildings, etc.) over distances from meters to kilometers is presented. Measurements are performed in three orthogonal axes (Z - laser beam, Y - vertical, X - horizontal) using interference wedge structures. The system incorporates a high-sensitivity technique for identifying parasitic vibrations, which can be addressed either by temporary suspension of data acquisition or through post-processing methods, including signal subtraction or elimination via oscilloscope-supported filtering and analysis techniques.
