High-speed grating interferometry

We present the most recent advances in fast X-ray grating interferometer and their applications. A dedicated setup for rapid scanning with a single grating and using filtered broadband illumination of an undulator source has been implemented. With this setup, grating interferometer tomographic scans can be achieved within few minutes owing to the filtered broadband beam and single-grating spatial harmonic imaging technique. Use of this system on the chemical processes happening in few millisecond time span is presented. This beam condition is very stable which is very difficult to achieve with the monochromatic beams. Tomographic phase volume rendering obtained with this beam condition is explained. We will also describe the new capabilities and applications.
