Abstract:
An oscillatory micromirror comprising:a cantilevered mirror surface; at least one torsion beam mounted on the cantilevered mirror surface; a support member surrounding at least a portion of the cantilevered mirror surface; at least one flexural beam; wherein: the cantilevered mirror surface is joinable to the support member by at least one torsion axis formed by the at least one torsion beam; the at least one flexural beam is located between at least one of the at least one torsion beam and the support member, the at least one flexural beam providing a flexural oscillation for inducing a torsional oscillation of the cantilevered mirror surface about the at least one torsion axis; and an amplitude of the flexural oscillation is substantially smaller than an amplitude of the torsional oscillation.
