Quadriwave Lateral Shearing Interferometry in an Achromatic and Continuously Self-imaging Regime for Future X-ray Phase Imaging
We present in this Letter a type of quadriwave lateral shearing interferometer for x-ray phase imaging. This device is based on a phase chessboard, and we take advantage of the large spectrum of the source to produce interferograms with a propagation-invariant contrast. Such a grating has been created for hard x-ray interferometry and experimentally tested on a synchrotron beamline at Soleil.
