A hollow-core photonic crystal fiber Fabry-Perot interferometric (HC-PCF-FPI) strain sensing system is proposed and demonstrated. The sensing system has an excellent multiplexing capability owing to the wide free-spectral range of the HC-PCF-FPI structure. Moreover, with a simple fast Fourier transform demodulation method, the proposed strain sensing system could be potentially applied in structural health monitoring.
