A Tunable Echelle Imager [PDF]
, 2000 We describe and evaluate a new instrument design called a Tunable Echelle Imager (TEI). In this instrument, the output from an imaging Fabry-Perot interferometer is cross-dispersed by a grism in one direction and dispersed by an echelle grating in the ...

Electron Fabry-Perot interferometer with two entangled magnetic impurities [PDF]
, 2006 We consider a one-dimensional (1D) wire along which single conduction electrons can propagate in the presence of two spin-1/2 magnetic impurities. The electron may be scattered by each impurity via a contact-exchange interaction and thus a spin-flip ...

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

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.

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.
