We present a new method capable of measuringthree-dimensionalmacroscopicvelocity fields in flowing granular media, based on image correlation of successive high-speed radiographsfrom three orthogonal directions. This “X-ray rheography”has the potential to be applied more generally to investigate transient features in various opaque systems.
