Fabry‐Perot Interferometers

open access: yesEos, Transactions American Geophysical Union, 1988
This third volume of the Cambridge Studies in Modern Optics is a comprehensive and authoritative treatise on the design, construction, and analysis of measurements from these multiple‐beam instruments. Its treatment of the Fabry‐Perot interferometer is highly mathematical and unified, weaving together in a coherent and consistent format the work of ...

Comparative statistical analysis of neutral wind in mid-latitude mesosphere / lower thermosphere based on meteor radar and Fabry—Perot interferometer data

open access: yesSolar-Terrestrial Physics, 2018
Studies of the upper atmosphere wind are very important both for understanding the mechanism of transformation of exposure energy into heating, movement and chemical activity of the atmosphere, and similar processes of energy transfer from lower to upper

The Experimental plan of the 4m Resonant Sideband Extraction Prototype for The LCGT [PDF]

open access: yes, 2006
The 4m Resonant Sideband Extraction (RSE) interferometer is a planned prototype of the LCGT interferometer. The aim of the experiment is to operate a powerrecycled Broadband RSE interferometer with suspended optics and to achieve diagonalization of ...

Investigation of Composite Structure with Dual Fabry–Perot Cavities for Temperature and Pressure Sensing

open access: yesPhotonics, 2021
To deeply analyze the influence of diaphragm materials on the temperature and pressure sensitivity of Fabry–Perot interferometer-based dual-parameter fiber sensors, the multiple transfer method was used to fabricate the dual Fabry–Perot cavities ...

Analysis of Dielectric Waveguide Grating and Fabry–Perot Modes in Elastic Grating in Optical Detection of Ultrasound

open access: yesSensors, 2021
In our previous work, we have demonstrated that dielectric elastic grating can support Fabry–Perot modes and provide embedded optical interferometry to measure ultrasonic pressure.

Miniature Twist/Rotation Fabry Perot Sensor Based on a Four-Core Fiber

open access: yesProceedings, 2018
This paper presents a miniature Fabry Perot twist/rotation sensor. The presented sensor consists of a single lead-in multicore fiber, which has four eccentrically positioned cores, a special asymmetrical microstructure, similar to a truncated cylinder ...

Model of Thermal Wavefront Distortion in Interferometric Gravitational-Wave Detectors I: Thermal Focusing [PDF]

open access: yes, 2002
We develop a steady-state analytical and numerical model of the optical response of power-recycled Fabry-Perot Michelson laser gravitational-wave detectors to thermal focusing in optical substrates. We assume that the thermal distortions are small enough

Miniature Fabry-Perot interferometer based on a movable microsphere reflector.

open access: yesOptics Letters, 2020
We propose and demonstrate a miniature Fabry-Perot interferometer (FPI) based on a movable microsphere reflector. The movable microsphere acts as a good reflector, with the reflections occurring at the spliced single-mode fiber/hollow-core fiber ...

Response of a New Low-Coherence Fabry-Perot Sensor to Hematocrit Levels in Human Blood

open access: yesSensors, 2014
In this paper, a low-coherence Fabry-Perot sensor with a spectrally measured signal processing response to the refractive index of liquids is presented.

Effects of Mirror Aberrations on Laguerre-Gaussian Beams in Interferometric Gravitational-Wave Detectors [PDF]

open access: yes, 2011
A fundamental limit to the sensitivity of optical interferometers is imposed by Brownian thermal fluctuations of the mirrors' surfaces. This thermal noise can be reduced by using larger beams which "average out" the random fluctuations of the surfaces ...
