The current status of optical fiber sensors is reviewed. The optical fiber sensors have certain
advantages that include immunity to electromagnetic interference, lightweight, small size …

We have developed a simple fiber optic Fabry-Perot interferometer (FPI) sensor that is used
to precisely monitor changes in the refractive index of gases. The operating principle of the …

A novel structure of the intrinsic Fabry-Perot interference (IFPI) fiber temperature sensor is
presented. The sensor uses two different core diameter fibers and produces a reflective …

A simple and highly sensitive phase-demodulation technique is proposed, and its use for a
fiber Bragg grating strain sensor is experimentally demonstrated. Sampling a phase …

The authors deliver a complete overview of fiber-optic Fabry-Perot (FFP) sensing
technology, integrating the knowledge and tools of multiple fields including optics, sensing …

This letter presents an intrinsic Fabry-Pe/spl acute/rot interferometric sensor fabricated by
splicing a section of multimode fiber in between two single-mode fibers. The fabrication …

This paper presents a high-sensitivity, all-silica, all-fiber Fabry-Perot strain-sensor. The
proposed sensor provides a long active length, arbitrary length of Fabry-Perot cavity, and …

The authors describe a passive technique for sensing the strain-induced wavelength shift of
a fibre Bragg grating (FBG) using a Mach-Zehnder interferometer that utilises a 3× 3 coupler …
