Abstract:
The present invention provides a single torsional hinge device, such as a mirror, adapted for use as a pivoting mirror and preferably a pivoting mirror oscillating at a resonant frequency about the single hinge. The single torsional hinge mirror reduces or substantially eliminates stresses on the torsional hinge mirrors caused by mismatched mounting levels of the support structure and/or differences of the coefficient and thermal expansion of materials in the mirror and support structures. The mirror may include a single layer of silicon having a reflective surface or may be a multilayered mirror wherein silicon is used for the torsional hinges and support and silicon or other materials may be used as the reflecting surface.
