Abstract: In a Michelson interferometer for producing optical path differences, from a beam divider, a deflection mirror, an externally silvered corner mirror, a collective lens and a radiation detector an input/output module is formed, from two rotating retroreflectors and two stationary retroreflectors an intermediate module is formed, and from two further rotating retroreflectors and from a bilaterally silvered plane-parallel plate a termination module is formed. The three modules can be combined to an interferometer in such a manner that the plane mirrors of the corner mirror of the input/output module are each arranged opposite a respective input-side half of the two rotating retroreflectors of the intermediate module and between said reflectors which in turn are arranged directly next to and adjacent the two further rotating retroreflectors of the termination module in such a manner that the output-side aperture halves of the two stationary retroreflectors are aligned opposite the input-side aperture halves of the two further rotating retroreflectors of the termination module. In operation the respective adjacent rotating retroreflectors of the modules fixedly connected to each other in exact match rotate in-phase with respect to their rotational angle position and in opposite phase of 180.degree. with respect to the corresponding opposite retroreflectors.
