Exploring the Versatility of Fabry-Pérot Interferometers: From Spectroscopy to Sensing
Abstract: The fundamental concept of operation for the Fabry-Perot interferometer is interference. Coherent light bounces back and forth between two extremely reflecting mirrors as it travels through the interferometer. The device operates on a pattern of constructive and destructive interference that is produced by this. By carefully regulating the space between the mirrors, a resonant optical cavity is created. The Fabry-Perot interferometer (FPI) is one of the most important and versatile …
