Abstract:
An actuator adapted to direct a light beam from a light source at a variable angle of incidence onto a pupil in a predetermined region of space, said actuator comprising a fixed base, support means mounted to be mobile relative to said base, optical means for pointing said beam on the path thereof between said source and said pupil and carried by said support means, and motor drive means connected to said support means to move them in a controlled manner, wherein said base and said mobile support means are connected to each other by at least one pair of flexible blades forming with them a substantially plane mount defining a general plane, the flexible blades of said pair are respectively aligned with two axes extending from said base toward a point of intersection in said plane, said blades are connected to said support means at two respective points between said base and said point of intersection of said axes, and said pointing means are adapted to deflect said beam in a variable manner in a plane parallel to said plane of said mount by moving said support means.
