Determination of complex transmissivity using x-ray in-line holography and two-beam interferometry.

A method for quantitative measurement of the complex transmissivity of samples is presented where in-line holography and additional shearing interferograms, at a fixed sample-detector distance, are used. The wave field at the detector plane is completely determined and the exit-face wave field of the sample is reconstructed by deconvolution. The principle of experiment and the results of imaging of various samples are described. [ABSTRACT FROM AUTHOR]
