Abstract

A technique for easy installation and usage of optical fiber strain sensors is presented. This technique allows reliable and accurate fiber positioning by means of a resin support in which optical sensing leads are embedded. Static and dynamic behavior of the optical strain gauge is investigated and its performance is compared to similar optical sensing systems either directly surface mounted on the structure or embedded into composite laminates. Comparisons to values derived from a semiconductor electrical strain gauges are also made.
