A mirror structure includes a mirror, a reflective face, a cut in the mirror under the face, and a torsion arm attached to the mirror. Such a mirror structure often distorts a scanned image less than prior mirror structures because the cut uncouples the twist-induced strain in the torsion arm from the mirror face, and thus reduces the level of deformation that this strain imparts to the mirror face. Another mirror structure includes a base formed from a first material, a mirror attached to the base and formed from a second material, and a torsion arm attached to the base. Such a composite mirror structure often distorts a scanned image less than prior mirror structures because it reduces the acceleration-induced bending of the mirror and/or the twist-induced strain in the torsion arm, and thus reduces the level of deformation that this bending and/or strain impart to the mirror face.
