Testing fast aspheric concave surfaces with a cylindrical null screen

Not Accessible

Your library or personal account may give you access

Abstract

A noncontact test procedure to obtain the shape of fast concave surfaces is described. A cylindrical null screen with a curved grid drawn on it in such a way that its image, which is formed by reflection on a perfect concave surface, yields a perfect square grid is proposed. The cylindrical null screen design and the surface evaluation algorithm are presented. Experimental results for the testing of an elliptical mirror of 164mm in diameter (f/0.232) are shown.
