Abstract
Beam scanning system includes a rotatable element for receiving a stationary light beam at successive element facets to thereby impart a scanning motion to the light beam so as to scan a beam receiving medium. Deviation in the mechanical or optical performance related to each successive facet are corrected by use of a high-speed beam deflector operated in either a closed loop or open loop servo system. The beam deflector includes a unique piezoelectric plate and reflecting body structure, wherein parallel plates of piezoelectric material are bonded at selected locations to a reflecting body with flexible adhesive. The plates are supported by a platform and operatively connected to a plate driving means to effect motion of the body in a push-pull arrangement with respect to the platform. The resulting structure has a high resonant frequency even though a reflecting body in the form of relatively large glass mirror may be employed.
