Abstract
The method disclosed comprises the steps of directing light to a plurality of modulators where each modulator comprises a mirror rotatably fixed to at least two support members displaced from all outer edges of the mirror and an electrode for rotating the mirror, selecting an angle through which the mirror is to rotate, generating a signal characteristic of the angle, applying the characteristic signal to the electrode, and rotating the mirror through the selected angle.
