1. A MEMS apparatus for scanning an optical beam comprising:

  • a. a mirror operative to perform a rotational motion to a maximum rotation angle around a mirror rotation axis; and

    b. a bouncing mechanism operative to provide a bouncing event and to reverse said rotational motion, wherein said bouncing mechanism includes at least one first comb drive stator;

    whereby said bouncing event provides said mirror with a piecewise linear response to actuation by intrinsically nonlinear forces.
