This PhD dissertation presents the optimization and design of a wavefront analyzer dedicated to optical metrology and phase imaging on synchrotron sources in the hard X-ray regime. We chose to develop a single grating interferometer combined with a phase retrieval algorithm based on Fourier analysis. The main purpose here is to conceive a bulk instrument able to work in a great variety of experimental conditions without having to tune the parameters of the instrument in between experiments. This is thus related to the key constraint that is to calibrate the wavefront analyzer so that any further measurements could be corrected from any deterministic errors and allow single shot measurements of any sample.The key varying parameter in synchro...
