Abstract
A steering mirror for use with a laser pattern generator. A reflective surface is mounted on a pivotally mounted extended member. A piezo electric crystal abuts the extended member and voltage applied to the crystal causes deformation of the crystal and ultimately movement of the reflective surface. A differential impedence transducer is coupled to the extended member to detect movement of the steering mirror. In this manner, the position of the mirror can be accurately controlled.
