ABSTRACT:
A light deflection device includes a deflection member having a sphere body enclosing a deflection face portion for deflecting a light beam, or a segmental sphere body having the deflection face portion and a segmental sphere face opposing to the deflection face portion. The device also includes a supporting member for supporting the deflection member in a turnable manner, and a driver for turning the deflection member. The driver is provided on the sphere face of the deflection member, and at a position opposing the sphere face or the segmental sphere face of the deflection member to apply a driving force to the sphere face or the segmental face. In one embodiment, a light deflection device array includes the arrangement of light deflection devices in a one-dimensional or two-dimensional array.
