Abstract

In order to resolve the disturbance of external perturbation in Weight-In-Motion (WIM) measurement by traditional methods, a novel pressure sensor for WIM of vehicles based on fiber ring-down spectroscopy is proposed here. A micro-bending sensing head is designed and its working principle is discussed in this paper. The fiber loop ring-down (FLRD) system reveals that the sensing forces applied to the sensing head can be obtained by measuring the ring-down time. Meanwhile, the velocity of vehicles is measured by analyzing two ring-down spectrums in this scheme. Experiment results show that the precision of velocity of vehicles is good and the sensor has a linear response to the applied force.
