Abstract: A Micro-Electro-Mechanical System (MEMS) interferometer provides for self-calibration of mirror positioning of a moveable mirror. The moveable mirror is coupled to a MEMS actuator having a variable capacitance. The MEMS interferometer includes a capacitive sensing circuit for determining the capacitance of the MEMS actuator at two or more known positions of the moveable mirror and a calibration module for using the actuator capacitances at the known positions to compensate for any drift in the capacitive sensing circuit.

Abstract: An interferometer wherein an incident beam from a radiation source hits a beam splitter at a first oblique angle of incidence and is split into a first, reflected partial beam, and a second, transmitted partial beam, that subsequently travel along separate arms of the interferometer. The first and second partial beams are respectively intercepted, reflected, and re-split to form returning beam portions and reflected and transmitted exit beam portions. A second terminal mirror and a folding mirror, which intercepts the second partial beam at a second oblique angle of incidence, are associated with the second interferometer arm and positioned orthogonal to the reference plane and on opposite sides of the exit path, so that a section of the second partial beam from the folding mirror to the terminal mirror and back to the folding mirror crosses the exit beam twice.
