Abstract

Simultaneous multi-parameter sensing using a cascaded chirp long period fiber grating (C-CLPG) is proposed, in which two resonance peaks are utilized for discriminating between strain and temperature. In the experiment, the applied strain and temperature changes are simultaneously determined within ±23 µε and ±0.14 °C, respectively.
