FabryPérotovy

FabryPérotovy refers to the Fabry-Pérot interferometer, an optical instrument invented by Charles Fabry and Alfred Pérot. It is characterized by two highly reflective parallel surfaces, typically mirrors, separated by a specific distance. Light entering the interferometer undergoes multiple reflections between these surfaces. These reflections cause constructive and destructive interference, depending on the wavelength of the light and the distance between the mirrors.

When the distance between the mirrors and the wavelength of the light satisfy specific conditions, constructive interference occurs, and light is transmitted. This results in a series of sharp interference fringes. The spacing and appearance of these fringes are highly sensitive to changes in the mirror separation or the refractive index of the medium between them.

The Fabry-Pérot interferometer is widely used in various scientific fields. It is employed for high-resolution spectroscopy, enabling the precise measurement of spectral line shapes and wavelengths. It also finds applications in optical filtering, laser cavity design, and distance measurements due to its sensitivity to optical path length variations. The resolution of a Fabry-Pérot interferometer is determined by the reflectivity of the mirrors and the finesse, a measure of the sharpness of the interference fringes.
