How does interferometry work?
The Michelson Interferometer, the best-known instrument in interferometry, was invented in 1887 by Albert Abraham Michelson, the first American to win a Nobel Prize in science. Michelson came up with a system of mirrors and translucent mirrors (beam splitters) to combine the separated light rays from the same source. Laser interferometry is a well-established method for measuring distances with exceptional precision.
Michelson interferometer diagram.
Usually, a single incident coherent light source beam will be split into two identical beams by the Michelson interferometer. Each of these beams travels a different route, called a path, and recombines before arriving at a detector. The difference in the distance each beam travels creates a phase difference between those beams. It is this phase difference that creates the interference pattern between the waves initially defined in the detector. If a single beam is split into two paths (measurement and reference), then the phase difference is the diagnosis of what changes phase along those paths. It could be a physical change along the path, or a change in the refractive index at which the beam travels.
