Abstract: The present invention is directed to an Interferometer (100) comprising a source (110) of a primary energy beam (111), a first reflector (120) being provided static such that a first path length from the source (110) to the first reflector (120) is constant, a reflector (1) with an energy beam reflecting surface (20) being provided by an outer surface of a sonotrode (10), wherein the reflector (1) is provided to oscillate such that a second path length from the source (110) to the reflecting surface (20) is variable, a target (140), a means for splitting an energy beam (160) arranged such that it divides the primary beam (111) into a first energy beam (112) incident onto the first reflector (120), and a second energy beam (113) incident onto the reflector (1) adapted to oscillate, and a means for combining energy beams (170) arranged such that it combines a third energy beam (114) reflected from the first reflector (120) and a fourth energy beam (115) reflected from the reflector (1) adapted to oscillate incident onto the target (140). Further provided is an infrared Fourier transform spectrometer (200).
