WebOct 1, 2024 · In conclusion, we developed an approach based on X-ray grating interferometry for investigating real-space variations in surface and interface … WebA point diffraction interferometer (PDI) is a type ... These problems are largely overcome in the phase-shifting point diffraction interferometer designs, in which a grating or beamsplitter creates multiple, identical copies of the beam that is incident on an opaque mask. The test beam passes through a somewhat large hole or aperture in the ...
