1. A method for periodically steering a beam of incident light through an angle comprising the steps of:

  • reflecting a beam of light off a mirror only comprised of reflective material fabricated monolithically so as to be suspended by at least two supporting elements, at least one of the supporting elements being displaced from an edge of the mirror, the elements forming an axis of rotation; and

    periodically applying a voltage to a first electrode fabricated monolithically with said mirror to cause the mirror to rotate about the axis of rotation, the first electrode being displaced outwardly from the axis of rotation in a first direction.
