An X‐ray LLL interferometer with a wedge‐shaped mirror plate is experimentally and theoretically investigated. Experimentally obtained interference patterns show that the Moiré fringes are superposed on Pendellösung fringes and the period of the Pendellösung fringes is not changed after passing the analyzer plate. An eikonal theory of interference‐fringe formation in an LLL interferometer with a wedge‐shaped mirror plate is developed, and provides predictions that coincide with experimentally obtained results.
