ABSTRACT:
An optical actuator directs an incident light beam from a light source onto a fixed surface external to the actuator at a variable angle. It directs the light beam onto a pupil in a predetermined region of space. A fixed base is attached to mobile supports which carry a mirror on the path of the beam. The supports are moved by a motor drive. The base and the supports are connected together by flexible blades aligned with two axes extending from the base toward a point of intersection. The mirror can therefore deflect the beam at a variable angle relative to the pupil.
