Abstract

A novel optical fiber sensor implementation for monitoring structural displacement and load is explored. This new sensor makes use of simple coupling losses between fibers in a hollow core sleeve, and as such, offers variable sensitivity, ruggedness, and design flexibility. Preliminary test results show promise towards the goal of making practical and cost effective fiber optic sensors for field use in structural monitoring. In addition to hardware tests, a computer simulation was written to model sensor performance, and critical design parameters were identified.
