ABSTRACT:
A method and apparatus for controlling the astigmatic focusing of a spherical mirror by adjusting the radius of curvature configuration thereof. Adjustment is made by applying a couple to the outer edge of the spherical mirror. A floating support mechanism prevents distortion of the variable curvature mirror as it is oriented at different tracking angles by applying a positive fluid pressure to the convex back surface of the mirror.
