interferentsimõõtur, mida kasutatakse ühest allikast tuleva valguse jagamisel saadud kahe kollimeeritud kiire suhteliste faasinihke variatsioonide mõõtmiseks
interferometer that use to determine the relative phase shift variations between two collimated beams derived by splitting light from a single source
The Mach–Zehnder interferometer has been used, among other things, to measure phase shifts between the two beams caused by a sample or a change in length of one of the paths.
