Appendix A2Basic Optical Interferometers

In addition to the Michelson configuration used in displacement measurements, several other optical interferometers are useful in electro-optical instrumentation. All of them serve the purpose of dividing the beams in a reference and a measurement arm, let the measurand affect the optical path, and recombine the beam to yield the interferometric signal of the type 1+cosΦ at the photodetector.

In this appendix, we will review the properties of basic optical interferometers, namely Michelson, Fabry-Perot, Mach-Zehnder, and Sagnac (Fig.A2-1). All these configurations are basic and can be improved by the addition of extra components or by suitable variants, like exemplified by the Michelson interferometer ...
