Fabry - Perot Interferometer
This short lecture note recalls some of the properties of Fabry-Perot interferome-ters. As an addition to textbooks , it may present some help to students working with such instruments.
متن کاملFabry - Perot Interferometer Prototype
A new Fabry-Perot Interferometer has been developed for the ADAHELI ADvanced Astronomy for HELIophysics solar satellite mission at the “Tor Vergata” University Solar Physics Laboratory. Fabry-Perot narrow filters are of great interest for the study of extended astronomical sources, such as the solar photosphere and chromosphere. The prototype instrument provides a high throughput that allows fo...
متن کاملExtrinsic Fabry-Perot interferometer fiber-optic microphone
In this paper we describe a new fiber-optic microphone developed as a passive acoustic sensor for traffic monitoring and vehicle classification. It is based on a fiber-optic extrinsic Fabry–Perot (FP) microinterferometer coupled to an external membrane for modulating the FP cavity length and a low coherent superluminescent diode as light source. The frequency characteristic as compared with a s...
متن کاملThree Cavity Tunable MEMS Fabry Perot Interferometer
In this paper a four-mirror tunable micro electro-mechanical systems (MEMS)Fabry Perot Interferometer (FPI) concept is proposed with the mathematical model. Thespectral range of the proposed FPI lies in the infrared spectrum ranging from 2400 to 4018(nm). FPI can be finely tuned by deflecting the two middle mirrors (or by changing the threecavity lengths). Two different cases were separately co...
متن کاملAnalytical Modelling of a Refractive Index Sensor Based on an Intrinsic Micro Fabry-Perot Interferometer
In this work a refractive index sensor based on a combination of the non-dispersive sensing (NDS) and the Tunable Laser Spectroscopy (TLS) principles is presented. Here, in order to have one reference and one measurement channel a single-beam dual-path configuration is used for implementing the NDS principle. These channels are monitored with a couple of identical optical detectors which are co...
