Abstract

In this work, we will show the procedure to design a null screen to evaluate a convex surface without symmetry of revolution, which is of great interest in developing optical devices. The process to obtain the shape of the surface without symmetry of revolution from images reflected from the null screen by the surface under test will be presented. In addition, we will present the experimental results of the test applied to a free-form surfaces. We will show the advantages of the method compared to others and its drawbacks.
