Paper Abstract

Testing profiles of aspheric surfaces at various stages of figuring is essential, and a simple algorithm for finding the surface profile is very helpful. In order to find the wave front fourth order spherical aberration, a new algorithm resorting to decenter and defocus is presented here.
