Abstract
The invention is a method of calibrating an X ray diffraction measuring system. The method includes moving a so-called calibration object along a propagation axis along which an irradiation beam propagates, the calibration object being adapted to occupy a plurality of successive positions along that axis. At each position of the object a spectrometry detector including at least one pixel acquires a spectrum of scattering radiation emitted by the object at an acute angle relative to the propagation axis. The method includes, in various spectra corresponding to various respective positions of the object, the identification of a so-called calibration peak and obtaining a parameter of said peak, which parameter can be the intensity or the energy of said peak. The parameters obtained on the various peaks then make it possible to establish an associated pixel dispersion function.
