Abstract

Different methods using optical fibers for real time inspection of concrete buildings and structures have already been investigated. According to recent progress it becomes more and more possible to obtain reliable punctual strain measurements with sophisticated techniques based on light polarization analysis. Based on knowledges about birefringence measurements in single-mode fibers which shows a fullness of information, this paper presents the difficulty of average strain measurement interpretation from beat length determination in homogeneous zones.
