INTERFEROMETER WITH AN OSCILLATING REFLECTOR PROVIDED BY AN OUTER SURFACE OF A SONOTRODE AND FOURIER TRANSFORM INFRARED SPECTROMETER
First Claim
1. An interferometer comprising:
- a source of a primary energy beam,a first reflector configured to be static during signal acquisition such that a first path length from the source to the first reflector is constant during signal acquisition,a reflector with an energy beam reflecting surface being provided by an outer surface of a sonotrode, wherein the reflector is provided to oscillate such that a second path length from the source to the reflecting surface is variable during signal acquisition, a target,a means for splitting an energy beam arranged such that it divides the primary beam into a first energy beam incident onto the first reflector, and a second energy beam incident onto the reflector adapted to oscillate, anda means for combining energy beams arranged such that it combines a third energy beam reflected from the first reflector and a fourth energy beam reflected from the reflector adapted to oscillate incident onto the target.

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).
