Related to Fabry-Perot Interferometer: Brewster's angle


 (ā′tə-lŏn′, ĕt′ə-)
A type of interferometer in which incoming light is repeatedly refracted and reflected between two surfaces into multiple beams that are then focused together, causing self-interference of the light.

[French étalon, standard (of weight or a unit of measurement), reference point, etalon (in reference to the fixed widths between the two surfaces in the first such interferometers), from Old French estalon, standard, of Germanic origin; akin to Middle Dutch stael, model, sample.]


(General Physics) physics a device used in spectroscopy to measure wavelengths by interference effects produced by multiple reflections between parallel half-silvered glass or quartz plates
[C20: French étalon a fixed standard of weights and measures, from Old French estalon; see also stallion]

A Fabry-Perot interferometer picks up the propagation of the sound, which is affected by the micro-structure of the steel, and translates the pulses into a digital signal for computer analysis.
