Reliable and accurate measurements of temperature and strain in structures subjected to
fire can be difficult to obtain using traditional sensing technologies based on electrical …

In-line fiber optic interferometers have attracted intensive attention for their potential sensing
applications in refractive index, temperature, pressure and strain measurement, etc. Typical …

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 …

In this paper we discuss the results obtained with an in-fiber Fabry-Perot interferometer (FPI)
used in strain and magnetic field (or force) sensing. The intrinsic FPI was constructed by …

Achieving a new generation of enhanced sensors requires the development of structures
that result from the fusion of different concepts and effects. In this paper, we combine a …

All-optical-fiber Fabry-Perot interferometers (FPIs) with microcavities of different shapes
were investigated. It was found that the size and shape of the cavity plays an important role …

We fabricate and experimentally demonstrate a hybrid structured Fabry–Perot interferometer
(FPI) embedded in the middle of a fiber line for simultaneous measurement of axial strain …

We report on the fabrication of a monolithic fiber Fabry–Perot interferometer whose cavity is
a microscopic air bubble. The latter is formed when splicing together a conventional single …

We experimentally demonstrate transverse load and strain sensing based on a fiber optic
Fabry-Perot interferometer (FPI) with special air cavity, which was created by fusion splicing …

Common-path optical coherence tomography (CPOCT) is known to reduce group velocity
dispersion and polarization mismatch between the reference and the sample arm as both …
