Simultaneous measurement of strain and temperature using Fabry–Pérot interferometry and antiresonant mechanism in a hollow-core fiber
نویسندگان
چکیده
A fiber-optic sensor for the simultaneous measurement of strain and temperature is proposed experimentally demonstrated based on Fabry–Pérot (FP) interference antiresonance (AR) mechanism. The was implemented using a single-mode fiber (SMF)–hollow-core fiber–SMF structure. sensitivity 21.11 pm/°C achieved by tracing troughs envelope caused AR mechanism, 2 pm/?? detecting fine fringes FP cavity. results indicate that dual-parameter stable reliable.

Twin-Core Fiber-Based Mach Zehnder Interferometer for Simultaneous Measurement of Strain and Temperature
In this paper we present an all-fiber interferometric sensor for the simultaneous measurement of strain and temperature. It is composed of a specially fabricated twin-core fiber spliced between two pieces of a single-mode fiber. Due to the refractive index difference between the two cores in a twin-core fiber, a differential interference pattern is produced at the sensor output. The phase respo...
متن کاملBroadband high birefringence and polarizing hollow core antiresonant fibers.
We systematically study different approaches to introduce high birefringence and high polarization extinction ratio in hollow core antiresonant fibers. Having shown the ineffectiveness of elliptical cores to induce large birefringence in hollow core fibers, we focus on designing and optimizing polarization maintaining Hollow Core Nested Antiresonant Nodeless Fibers (HC-NANF). In a first approac...

15 صفحه اولSimultaneous measurement of strain and temperature by use of a single-fiber Bragg grating and an erbium-doped fiber amplifier.
We propose and demonstrate a novel sensor by using a single-fiber Bragg grating that can simultaneously measure strain and temperature with the aid of an erbium-doped fiber amplifier. By using a linear variation in the amplified spontaneous emission power of the erbium-doped fiber amplifier with temperature, we determine the temperature. By subtracting the temperature effect from the fiber Brag...
