Paper Abstract

A fiber optic force sensor system based on supercontinuum radiation is developed. Short pulse (175fs) generated from mode-locked Erbium-doped fiber (EDF) laser was broaden and extended from 1300 to 1700nm after passing through Photonic Crystal Fiber (PCF). The spectrum shift of this broadband continuum has a strong function to the change of PCF birefringence induced by external force on PCF and exhibits a good sensitivity of 0.53604 nm/N and an excellent repeatability. Thus, the proposed system is proven to be a novel instrumentation for the transverse force measurement with many potential applications in smart structure.
