Fiber Optic Fabry-Perot Current Sensor Integrated with Magnetic Fluid Using a Fiber Bragg Grating Demodulation

Sensors, 2015
An optical fiber current sensor based on Fabry-Perot interferometer using a fiber Bragg grating demodulation is proposed. Magnetic fluid is used as a sensitive medium in fiber optical Fabry-Perot (F-P) cavity for the optical characteristic of magnetic ...

Development of a frequency-detuned interferometer as a prototype experiment for next-generation gravitational-wave detectors [PDF]

, 2005
We report on our prototype experiment that uses a 4-m detuned resonant sideband extraction interferometer with suspended mirrors, which has almost the same configuration as the next-generation, gravitational-wave detectors.

New technique to measure the cavity defects of Fabry-Perot interferometers [PDF]

, 2019
(Abridged): We define and test a new technique to accurately measure the cavity defects of air-spaced FPIs, including distortions due to the spectral tuning process typical of astronomical observations.

Pulsed laser linewidth measurement using Fabry–Pérot scanning interferometer

Results in Physics, 2016
We apply the Fabry–Pérot (FP) scanning interferometer, which is normally used for continuous wave (CW) laser linewidth measurement, for the measurement of pulsed laser linewidths.
