Abstract


With the measurements of the local radii of curvature of an aspherical optical, convex or concave surface, the shape of the surface can be found. In this paper a method is proposed for taking radius measurements, for off-axis sections of an optical surface, using a retrocollimated interference method (rim) that was previously developed by several authors[1-3]; but in particular, in this paper, the one described by Xiang[4] for measuring long radii of curvature[5,6] is used.
