Abstract:
A positioner for articulation of an optical element within a plane, comprising:a frame; a moveable stage, coupled to the optical element; a first arm, having at a first end a first coupling to the stage, and having a second end adapted to receive a first encoded translator referenced to the frame, the first encoded translator articulating the first arm with a first drive component parallel to the plane; and a second arm, having at a first end a second coupling to the stage, and having a second end adapted to receive a second encoded translator referenced to the frame, the second encoded translator articulating the second arm with a second drive component parallel to the plane, wherein at least one of the first coupling and the second coupling to the stage is a one-axis rotary flexure having a pivot axis with an axial component perpendicular to the plane.
