High Sensitivity Transducer for Fibre-Optic Pressure Sensing Applied to Dynamic Mechanical Testing and Vehicle Detection on Roads

This paper describes fiber-optic sensor systems developed for airport ground traffic monitoring and the first steps toward their installation in an experimental surface movement guidance and control system (ESMGCS) at the Braunschweig airport. Initial results obtained with fiber-optic light barriers and vibration sensors are reported. The feasibility of employing interferometric strain gauges for this application will be discussed based on sensor characteristics obtained through measurements of dynamic load variations in an aircraft structure in flight.

“…Recently however, the focus of the applications has also centered around the field of civil engineering with aims at exploring the possibilities of embedding, prior to curing, optical fiber sensors into reinforced concrete elements and structures such as buildings, bridges, dams and tanks for the NDE of structural integrity and the measurement of the internal state of stress. Subsequently, a small number of researchers in the U.S. and Europe have been working on different ways to measure stress and strain in concrete using optical fibers [3][4][5][6][7][8][9][10][11][12][13][14][15] as well as to determine the health condition in a building [16].

In this paper an analysis is presented on the use of embedded optical fiber sensors in concrete elements and structures for the non-destructive measurement of internal stress and strain as well as for the assessment of structural integrity. A dicus8ion of the fundamental materials and micro-mechanical aspects regarding the fiber/matrix interaction is given. In addition, a summary of the experimental results obtained to date is made along with the applications sought for this new technology.

“…1,2,3,4,5,6,7 Newness, this time, lies in the fact that this sophisticated fiber optic WIM system has been characterized in both static and dynamic conditions. Since two sensors were deployed on a real French roadway, these dynamic conditions really illustrate fiber optic WIM technique capabilities.…”

This paper shows the way to turn a defect inherent to single-mode fiber, namely birefringence, into a prime quality for a powerful and reliable sensor. The latter is entirely devoted to Weigh-In-Motion (WIM) applications extended to complete active traffic management systems. After a brief description of the sensor and its principle of operation, the theoretical model is developed. Then, a full characterization made in both static and dynamic conditions is presented. The results obtained illustrate how it is difficult to interpret a weight measured in dynamic conditions and correlate the value with the static weight.
