Abstract

A high-precision dual-parameter simultaneous measurement sensor was proposed and developed by cascading a fiber Bragg grating (FBG) and a hollow-core Bragg fiber (HCBF) with a length of 5 mm. Due to the anti-resonant mode in the HCBF and its unique hollow structure, the transmission spectrum exhibits periodic resonance dips with high visibility and low transmission loss. Experimental results demonstrate that the resonance wavelength dips of the transmission spectrum are independent to the length of the HCBF. The HCBF sensor and FBG have different temperature (21.02 pm/℃ and 10.95 pm/℃, respectively) and strain sensitivities (−0.58 pm/με and 0.98 pm/με, respectively), which enables simultaneous measurement of both temperature and strain by employing a 2 × 2 sensitivity coefficient matrix.
