Abstract

When testing an aspheric wavefront with any digital interferogram evaluation method, like phase shifting interferometry, Fourier interferometry, or with a spatial carrier analysis, there is a limit to the maximum degree of asphericity if a null compensator is not used. An analysis of this limitation using different interferogram interpretation methods are described.
