Abstract
A micro mirror positioning device includes a stationary vertical element, a stationary horizontal element and an interference eliminator. The stationary horizontal element holds micro mirrors in place during transportation for avoiding vibration and collision. The stationary vertical element accurately orientates the micro mirrors in the vertical position. The interference eliminator assures that the micro mirrors are free from the interference caused by the operating magnetic field of other micro mirrors in the micro mirror array, or external magnetic field, thereby preventing the magnetic field from interfering the overall operation of the micro mirror array.
