Abstract

A method is for calibrating an X-ray measuring facility. The method includes preparing the facility for measurement for a resolution of a plurality of different energy intervals; positioning a test object in a beam path of an X-ray beam; irradiating the test object via the X-ray beam, and during the irradiating, an intensity measurement of the test object appropriately resolved according to the energy intervals is carried out by the facility; determining an absorption function of the test object using the intensity measurement; preparing one of the energy intervals as a reference interval such that the absorption function has a negligible energy dependency over the reference interval; determining a correction function of the absorption function, for at least one further energy interval of the energy intervals, using at least one value of the absorption function in the reference interval; and calibrating the facility using the correction function determined.
