Temperature-Compensated Refractive Index Measurement Using a Dual Fabry–Perot Interferometer Based on C-Fiber Cavity

IEEE Sensors Journal, 2020
We demonstrate a simple-to-fabricate, temp- erature-compensated refractive index sensor using a dual Fabry–Perot optical fiber interferometer using C-fiber.

Multiplex Fabry-Perot interferometer

SPIE Proceedings, 1991
The Fabry-Perot interferometer (FPI) traditionally has been used to examine either small spectral ranges or relatively imple spectra. Recently, however, studies have shown that the FPI can be competitive with the Michelson interferometer ver extended spectral ranges.

Jamin Fabry–Perot interferometer

Optics Letters, 2003
A novel type of interferometer was designed and tested experimentally. It combines the advantages of the spatial path separation used in the two-wave polarized Jamin interferometer and the high sensitivity that characterizes the multiwave Fabry-Perot interferometer. Furthermore, when it is sandwiched between crossed polarizers it shows a sensitivity to

Feedback Stabilized Fabry-Perot Interferometer

Applied Optics, 1973
A method of stabilizing a Fabry-Perot interferometer with respect to a reference wavelength, while simultaneously stabilizing the parallelism of the flats, is described. The method consists of creating correcting signals proportional to the displacement of the fringe maxima of three auxiliary spectral sources with respect to a fixed reference point and

A High Temperature Sensor Based on Sapphire Fiber Fabry-Perot Interferometer

IEEE Photonics Technology Letters, 2020
A sapphire fiber high temperature sensor based on Fabry-Perot interference was studied in the paper. A sapphire wafer served as the Fabry-Perot cavity was fixed to the end face of the sapphire fiber. The sensor was encapsulated in an alumina ceramic tube-

Measurement of high pressure and high temperature using a dual-cavity Fabry-Perot interferometer created in cascade hollow-core fibers.

Optics Letters, 2018
A compact dual-cavity Fabry-Perot interferometer (DC-FPI) sensor is proposed and demonstrated based on a hollow-core photonic bandgap fiber (HC-PBF) spliced with a hollow-core fiber (HCF).
