    Abstract: A diffractive component comprises a grating (25) including plural regions (A, A', B) of different types, wherein the gratings in the different regions differ with respect to lattice period and orientation. The different regions can be arranged according to an irregular pattern. Further, the gratings of the different types can be inverse to each other, or parameters of grating forming structures can vary between regions of the different types. A structural parameter of a dual grating is determined using a first phase function of the dual grating. A deviation of a surface of an optical element from a target surface is determined in an interferometric measurement using a second phase function of the dual grating taking into account the determined structural parameter of the grating. In an interferometric method using a diffraction grating harbouring different phase functions in different types of regions arranged in a superlattice for measuring a surface of an object perturbing superlattice diffraction orders are destructively interfered by adapting the diffraction grating having a periodicity of the superlattice that varies across the grating.
