Theoretical fringe profiles with crossed Babinet compensators in testing concave aspheric surfaces.
This paper presents the theory for the use of crossed Babinet compensators in testing concave aspheric surfaces. Theoretical fringe profiles for a sphere and for an aspheric surface with primary aberration are shown. Advantages of this method are discussed.
