ABSTRACT:
Four loudspeaker voice coils are positioned in quadrature relationship, and a movable mirror support member is provided, having a mirror on a central hub portion, and having four outwardly extending orthogonal lightweight struts, each attached to an associated voice coil armature at a terminal strut portion. Jitter cancellation of a jittery incoming light beam directed at the mirror is effected by adjustment of tip/tilt AC generators coupled to the voice coils.
