Abstract

Recently, Onera developed a new interferometer for X-ray phase contrast imaging. This device uses a single phase grating and takes advantage of the incident light spectral bandwidth to create an achromatic and propagation-invariant pattern. This very simple setup produces highly contrasted interferograms after a certain distance of propagation. Our first quantitative images are presented in this paper and the performances of the device are discussed.
