الوصف: This paper introduces an innovative design for a laser-based apparatus employing diffractive beam sampling technology, with the primary purpose of characterizing vibration frequencies induced within large-scale bridges. The functioning principle of the device hinges upon its ability to discern minute alterations in the relative positions of a subset of the laser beam, resulting from the oscillatory behavior of a laser pendulum mechanism. The captured dynamic variations are seamlessly integrated into a real-time monitoring framework through the utilization of an adept image sensor, complemented by sophisticated software functionalities. Noteworthy for its amalgamation of straightforward implementation and remarkable precision, the proposed methodology stands as a potent instrument poised to ensure the secure and robust surveillance of the structural well-being of large-scale bridges.
