A proposed new X-ray interferometric method of measuring the coherence length of radiation (CLR) of X-rays was analyzed, and a special X-ray monolithic interferometer was designed, created, and tested to measure the X-ray CLR. The CLRs of the X-ray radiation CuK α 1 , NiK α 1 , CoK α 1 , and MoK α 1 sources were experimentally measured, and their CLRs and durations of coherent radiation (DCR) were theoretically determined. The suggested method and conducted experimental measurements were based on the disappearance of X-ray interference patterns depending on the path difference of superimposed X-rays. It has been experimentally proven that the X-ray interference patterns disappear when the path differences become greater than the corresponding X-ray CLRs. It was shown that experimentally determined CLRs of studied X-ray sources are in good agreement with theoretical calculations. It has been proven that this X-ray interferometric method and the corresponding monolithic L–L–L-type interferometer are quite suitable for measuring the CLR for various X-rays.
