ABSTRACT:
The present invention relates to a device for use in deflecting a concentrated light beam in two coordinates, for example, of a polar coordinate system. In this regard, the device utilizes a mirror that may be controllably tilted or oscillated about an axis of oscillation and that may also be rotated to any angular position (0 to 2π) about an axis of rotation. In this regard, the mirror may be tilted in any one of a number of planes passing through the intersection point of the axis of oscillation and axis of rotation. Furthermore, the mirror may be oscillated between first and second angular positions or tilted to a fixed angle relative the axis of oscillation, in conjunction with controlled movement around the axis of rotation. In this regard, a device is provided wherein the mirror has multiple degrees of freedom allowing for a plurality of beam deflection applications.
