Abstract
The structure of the invention serves to support mirrors defining a reflective channel, which can dynamically be reciprocally widened and narrowed, as in a two-beam interferometer. It is effectively divided, by pivot points on an intermedial axis, into two opposite portions of equal mass, thus affording to the structure immunization against translational forces transmitted through those points. The opposite portions also have their centers of gravity remotely located, so as to generate a counteracting torque in response to moments of rotational inertia transmitted through the pivot points. In the structure, integrally formed planar pieces are assembled to provide contiguous elongate elements and an interposed connecting web element, a plurality of which web elements produce a flexure joint.
