Fiber optic interferometers

Fiber optic interferometers are employed to measure different physical magnitudes such as temperature, strain, pressure or refractive index. In this post we will explain the basics of interferometry and the different types of existing interferometers: Michelson, Fabry-Perot, Sagnac, Mach-Zehnder, Moiré, the modal interferometer and white light interferometry.
