Interferometer for quantitative phase contrast imaging and tomography with an incoherent polychromatic x-ray source

摘要

An interferometer for X-rays, in particular hard X-rays, for obtaining quantitative phase contrast images, includes a standard polychromatic X-ray source, a diffractive optical beam splitter other than a Bragg crystal in transmission geometry, and a position-sensitive detector with spatially modulated detection sensitivity.
