A direct measurement of three‐dimensional X‐ray velocimetry with micrometer spatial resolution is presented. The key to this development is the use of a Laue crystal as an X‐ray beam splitter and mirror. Three‐dimensional flow velocities in a 0.4 mm‐diameter tubing were recorded, with <5 µm spatial resolution and speeds of 0.7 mm s −1 . This development paves the way for three‐dimensional velocimetry in many cases where visible‐light techniques are not effective, such as multiphase flow or flow of optically opaque liquids.
