Preliminary Study on LiDAR Performance in Vibration Measurement
LiDAR has evolved into a non-contact vibration sensor, unlocking new opportunities in structural health monitoring, industrial machinery, and civil engineering. This preliminary study evaluates the efficacy of LiDAR in non-contact vibration measurement through the utilization of COMSOL Multiphysics software simulations across various objects to determine time-of-flight (ToF). Results showed that performance improved with increased distance, particularly along the x-axis direction. The shortest ToF was recorded 3.31 ns for a rectangular object at 0.5 m, while the longest readings were observed at 7.5 m for the hemisphere shape. From the findings, it was confirmed that extended distances resulted in longer laser pulse travel paths, exhibiting a slope of 6.6898 ns/m for non-vibrating objects, laying the groundwork for future applications in the monitoring of vibration measurement.
