ABSTRACT:
An optical deflecting device has a supporting member and a deflecting member. The supporting member is provided with an opening. The arced inner surface of the opening corresponds to spherical annulus. The deflecting member has an arced ring-shaped wall and a plane mirror. The arced ring-shaped wall is in slidable contact with the arced inner surface of the opening. Driving mechanisms are provided on each of two perpendicular axes. The point of intersection of the two axes being a center of the spherical annulus. The driving mechanisms rotate the deflecting member around the two axes.
