Microbubble based fiber-optic Fabry-Perot interferometer formed by fusion splicing single-mode fibers for strain measurement.
TLDR
An all-fiber optical Fabry-Perot interferometer (FPI) strain sensor whose cavity is a microscopic air bubble is demonstrated and strain and temperature sensitivities are studied experimentally.Abstract:
We demonstrate an all-fiber optical Fabry–Perot interferometer (FPI) strain sensor whose cavity is a microscopic air bubble. The bubble is formed by fusion splicing together two sections of single-mode fibers (SMFs) with cleaved flat tip and arc fusion induced hemispherical tip, respectively. The fabricated interferometers are with bubble diameters of typically ∼100 μm. Strain and temperature sensitivities of fabricated interferometers are studied experimentally; a strain sensitivity of over 4 Pm/μe and a thermal sensitivity of less than 0.9 Pm/°C is obtained.read more

Recent progress in fiber-optic extrinsic Fabry–Perot interferometric sensors
TL;DR: In this article, the optical amplification technology is adopted into the EFPI sensor system to enhance the interferometric signal considerably, and both spatial-frequency multiplexing and coarse-wavelength division multiple-xing technologies are demonstrated for the Fizeau sensor in order to realize the measurement of multiple parameters such as displacement, transverse load, static strain, temperature, and vibration.

Micro Fabry-Perot interferometers in silica fibers machined by femtosecond laser.
TL;DR: Investigation of the strain and temperature characteristics of the two MFPIs with an identical cavity length show that the strain sensitivity of the PCF- based MFPI is smaller than that of the SMF-based M FPI due to their different waveguide structures, while the twoMFPIs have close temperature sensitivities due to the similar host materials.
