magnetostriction with the michelson interferometer
... In a Michelson interferometer, the light beam is split by a half-silvered glass plate into two partial beams (amplitude splitting), reflected by two mirrors, and again brought to interference behind the glass plate (Fig. 2). Since only large luminous spots can exhibit circular interference fringes, ...
