Abstract
A method reduces movement of a reflector in an unintended mechanical mode during movement of the reflector in an intended mechanical mode. The method includes using a reflector driver to apply a distribution of forces to the reflector so as to move the reflector in both the intended mechanical mode and in the unintended mechanical mode. The distribution of forces is applied at a resonant frequency of the unintended mechanical mode. The method further includes adjusting the reflector driver to alter the distribution of forces applied to the reflector such that the movement of the reflector in the unintended mechanical mode is reduced.
