• A new approach is proposed for fast recording Reciprocal Space Maps (RSM) of crystals without using mechanical systems. It is based on the simultaneous use of two Adaptive Bending X-ray Optics (ABXO) elements made of lithium niobate crystals located on a laboratory X-ray diffractometer at the positions of the monochromator and analyzer. The technique has been tested on a model silicon crystal. It was shown that the proposed technique allows fast and precision measurements of the RSM, providing significant progress both in speed (up to 30 times) and accuracy of the data (up to 3 times) obtained. It opens up opportunities for studying the evolution of the defective structure of various prospective crystalline materials under external loading.
