The Comparison of Environmental Effects on Michelson and Fabry-Perot Interferometers Utilized for the Displacement Measurement

Sensors, 2010
The optical structure of general commercial interferometers, e.g., the Michelson interferometers, is based on a non-common optical path. Such interferometers suffer from environmental effects because of the different phase changes induced in different ...

High-spectral-resolution Fabry-Pérot interferometers overcome fundamental limitations of present volcanic gas remote sensing techniques

Frontiers in Earth Science, 2023
Remote sensing (RS) of volcanic gases has become a central tool for studying volcanic activity. For instance, ultraviolet (UV) skylight spectroscopy with grating spectrographs (GS) enables SO2 (and, under favourable conditions, BrO) quantification in ...

A theoretical-practical study on poles and zeros calculated from a filtered modulated function of an interference pattern

Results in Physics, 2021
In this work, it is reported that the interference pattern produced by an interferometer can be studied on the s-plane and its modulated function having three poles and two zeros over the imaginary axis.

Optimizing Vernier Effect Sensitivity Through Smaller Cavity Sensor Design [PDF]

EPJ Web of Conferences
This work demonstrates the sensitivity dependence on the chosen cavity length for the sensor Fabry-Perot interferometer (FPI), where the smaller cavity exhibits a higher magnification factor compared to the situation when the cavity length is larger than

A nanostructured Fabry-Perot interferometer

Optics Express, 2010
A polymer-based micromachined Fabry-Perot interferometer (µFPI) with embedded nanostructures in its cavity, called nanostructured-FPI, is reported. The nanostructures inside the cavity are a layer of Au-coated nanopores. As a refractive-index sensitive optical sensor, it offers the following advantages over a traditional µFPI for label-free biosensing ...
