Wavefront precise analysis by means of nulling interferometer

Express analysis of wavefront by means of nulling interferometer is proposed. Nulling interferometer performs an achromatic measurement of wavefront in a wide spectral window from visible to near infra-red. The wavefront transformation in a nulling interferometer and the extreme precision of wavefront control are reported.
