Abstract: A Fourier-transform interferometer with self-apodization compensation comprises at least one pair of mobile prisms forming a plate with thickness which varies at the same time as an optical path length difference is itself varied. The prisms are displaced using a mobile system with a single degree of freedom, comprising two support elements and at least two rotatably hinged levers. The interferometer is adapted to be installed on board a satellite, for spectral analysis of a radiation originating from the Earth's surface.

Abstract: Interferometric transform spectrometer (ITS) systems and methods of operation thereof. In one example, an ITS system includes a Michelson interferometer that introduces a varying optical path length difference (OPD) between its two arms so as to produce an interferogram, a detector that receives and samples the interferogram, and a scan controller coupled to the detector and to Michelson interferometer. The scan controller controls the Michelson interferometer to vary the OPD in discrete steps such that the detector provides M samples of the interferogram for each of two scan segments. In the first scan segment, the M samples have a uniform or non-uniform sample spacing and the OPD has a first maximum value. In the second scan segment, the M samples have an incrementally increasing sample spacing and the OPD has a second maximum value that is at least twice the first maximum value.

Abstract: An interferometer includes a first assembly having a base, a beam splitter assembly to split light into first and second portions, and a fixed mirror for reflecting the first portion of light; and a second assembly movable with respect to the first assembly, and having first and second scan carriages, and a movable mirror connected to the second scan carriage for reflecting the second portion of light. The beam splitter assembly combines the reflected first and second portions of light into a recombined radiation beam. Inner bearing flexures enable movement of the first scan carriage relative to the base, and outer bearing flexures enable movement of the second scan carriage relative to the first scan carriage, such that a plane containing the movable mirror is maintained parallel to multiple planes containing the movable mirror at respective distances between the second and first assemblies during scan movement of the movable mirror.

Abstract: An all-graphite interferometer bearing assembly is introduced that allows the movement of a movable mirror in a Michelson interferometer without degradation during use. The assembly includes a stationary hollow graphite tube and a movable assembly which includes a mirror and a monolithic graphite member slidably disposed within the bore of the graphite tube that is composed of the same grade of graphite material as the monolithic graphite member. The result is a robust novel moving mirror arrangement in a Michelson interferometer that enables precise mirror alignment control, a long stroke length, excellent vibration damping and reduced sensitivity to external vibrations.
