Currently, in the work of structural inspection and verification, the measurement of structural fluctuations in the form of dynamic load is always one of the necessary works to evaluate the structural capacity. Due to the current methods of electronic sensors attached directly to the structure, the measurement met many difficulties. These difficulties stem from the fact that sensors are often located in difficult-to-reach positions such as high places and obstacles. Sensor mounting surface is difficult to mount, and measurement costs often increase due to the addition of scaffolding, ladders, and measurement work often takes time. To solve this problem, the new solution is to use laser measuring equipment to measure displacement and acceleration remotely. Research paper on application of laser measurement technology to measure fluctuations in structures. The content of the paper includes working principle analysis, solution application experiments and solution feasibility.
