Differential phase contrast imaging can provide direct access to electron density, and dark field (or small angle scatter) contrast enables access to surface and texture details significantly below the detector resolution. These new imaging capabilities offer the opportunity to image soft tissue for medical applications, or liquids and low density powders for aviation security applications. In contrast to sources for optical interferometers, X-ray sources are incoherent, requiring external means to create partially coherent photons.
