COMPARING POLYMER OPTICAL FIBER (POF), FIBER BRAGG GRATINGS AND TRADITIONAL STRAIN GAUGE FOR AIRCRAFT STRUCTURAL HEALTH MONITORING

摘要

Recently, the Polymer Optical Fiber Application Center (POF AC) at the University of Applied Sciences, Nuremberg has developed a polymer optical fiber (POF) elongation sensor. This work analyzes if this design could substitute the traditional strain gauges that are commonly used in Structural Health Monitoring (SHM) tests, or the quite recent sensors based on fiber Bragg gratings.
