Abstract
An alignment and path length control apparatus having a mirror housing having a base and a closed wall. The base has a mirrored external surface. The closed wall has a central axis. The closed wall is joined to the base at a base end of the closed wall by a flexible web. The closed wall extends above the base and terminates at a rim defining an aperture. The base has a central region coupled to the cylindrical wall. A post extends from the central region of the base within the cylindrical wall to a top end. A mirror axis extends from the mirrored external surface through the post. The central axis is substantially parallel to the mirror axis. An alignment transducer responds to a first alignment control signal by applying at least a first force between the post and the wall to deflect the mirror axis with respect to the central axis. A linear transducer responds to a linear displacement control signal by applying an axial force to the post to displace the central region longitudinally along the central axis.
