SACRAMENTO-SOLANO, J. D; GRANADOS-AGUSTIN, F.S  and  CORNEJO-RODRIGUEZ, A.A. Measurements of local radii of curvature by the retrocollimated interferometric method. Rev. mex. fis. [online]. 2008, vol.54, n.3, pp.194-199. ISSN 0035-001X.

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.

Keywords : Retrocollimated; interference; radii of curvature.
