The system is based on a single-shot grating interferometer [2, 3] and a thin diamond single-crystal beam splitter. The beam splitter is designed to be inserted in the incident and oriented to diffract a fraction of the incident beam bandwidth into the interferometer, for wavefront measurement and reconstruction. The concept is intended to study the feasibility of a non-invasive wavefront sensor for real time wavefront monitoring and diagnostics, with possible application in adaptive mirrors for wavefront preservation and control [1, 4]. The design focus was on compactness to enable easy portability and implementation in a beamline.
