FIBRE OPTIC SENSORS FOR TRAFFIC MONITORING APPLICATIONS

In this paper, the authors describe the use of fiber optic sensors for vehicle monitoring applications. The fiber optic cables are installed inside the asphalt layer of the road and are able to measure compression or vibrations. Two types of sensors were used. One was based on the microbending effect while the other used the speckle phenomena. The paper discusses the advantages and disadvantages associated with both types of sensors. Field test results are also presented.
