Abstract

Xiang developed a method for the measurement of radii of curvature of optical surfaces greater than one meter, this method is used for spherical concaves and convexes surfaces, at the vertex; the error is of 0.1%. In this work are carried out some innovations to the method of Xiang, for measurements of local radius of curvature of conical concaves and convexes surfaces. Some results obtained are for a parabolic surface.
