Abstract: A novel means of provided a hybrid flexure mounted moving mirror component in an interferometer is introduced herein. In particular, a linear bearing in combination with a novel flexure mounting having novel tilt and velocity control of the moving optical component is provided. Such an arrangement enables correction of the errors at the mirror itself while also solving the problem of isolating vibration and noise caused by the imperfections in the bearing surfaces used in many conventional interferometers. Using such a coupled flexure mounting of the present invention, in addition to the above benefits, also enhances velocity control because the resultant low mass of the moving mirror assembly enables the systems disclosed herein to respond faster than conventional mirror velocity controlled interferometer instruments and with a lower velocity error so as to provide a more stable and lower noise spectra from the analytical instrument.

Abstract: A two-beam interferometer for Fourier Transform spectroscopy has a double pivot scanning mechanism. The interferometer has two rigid pendulums that are each rotatable to swing around an associated one of distinct axes of rotation. A linkage links the two rigid pendulums to each other and constrains their rotation relative to each other. The interferometer has bearings, which may be flexure bearings, for rotatably mounting the two pendulums to swing around an associated one of the distinct axes of rotation and a first and a second bearing linking the linkage to an associated one of the pendulums. The two rigid pendulums, the linkage and the bearings can be a monolithic structure.
