Fbg Sensors

Instrumentation techniques, implementation and installation methods are major concerns in today’s distributed and quasi-distributed monitoring applications using fiber optic sensors. Although many successful traffic monitoring experiments have been reported using Fiber Bragg Gratings (FBGs), there has been no standardized solution proposed so far to have FBG seamlessly implemented in roads. In this work, we investigate a mobile platform including FBG sensors that can be positioned on roads for the purpose of vehicle speed measurements. The experimental results prove the efficiency of the proposed platform, providing a perspective toward weigh-in-motion systems.

Accuracy And Repeatability

A new line of fiber-optic sensors suited for structural and geotechnical monitoring purposes is presented. A Fabry-Perot strain gauge is contained in each of the new sensors introduced here: four embedded and surface-type strain gauges and one type of temperature gauge. Described here are the working and reading principles of the basic Fabry-Perot strain gauge. One of the gauge’s features that allows for temperature-compensated or noncompensated measurements is described, and the various sensors constructed around the gauge are presented. These newly developed sensors exhibit high accuracy and repeatability, as illustrated by various calibration tests reported here.
