This drift is due to systematic positioning errors that occur when the zone plate Z-axis stage moves, and has two parts: +- **Real Drift**: caused by the ZP stage not moving parallel to X-ray beam axis. +- **Virtual Drift**: caused by the interferometer mirror surface not being parallel to the ZP stage movement. + + \ No newline at end of file
