Abstract

An optical scanning system includes a light source to generate a light beam. An oscillatory microelectromechanical system including a mirror deflects the light beam in a predetermined manner. The light source and microelectromechanical system are formed in a silicon substrate. Rotational shafts in the microelectromechanical system facilitate oscillatory movement of the mirror.
