Abstract
A dynamic optical path length modulator for optical interferometry, holography and tomography is disclosed. The optical path length in a beam path is changed in that the light beam in question is guided through a double mirror arrangement which is formed of two plane mirrors which are parallel to one another and are rotatable about a common axis. A path length-dependent dispersion of any desired magnitude can be introduced into the beam path by the arrangement of plane plates and prisms.
