Abstract
Abstract A light deflection device is comprised of a cantilever member, a light deflecting element provided near the fixed end of the cantilever member, and a means of imparting deflection to the free end of the cantilever member, so that the angle of inclination of the light deflecting element, and hence the angle of deflection of the light, can be set and controlled with very high precision by the controlled deflection of the cantilever member by said means.
