Vibratile optical boresight

摘要

A vibratile optical boresight which can be used for conical or nutating scanning of a target by a beam of light. A lens is mounted for vibration, in at least one direction in a plane normal to the axis of the lens, between the free ends of piezo-electric cantilevered plates which are trihedral, tapering towards the free ends. The lens is carried in a canister which has arms extending to the cantilevers. The arms and the cantilevered plates can flex in a common plane to which the axis is normal.
