  • Publication number: 20200352533
    Abstract: A method and system for detecting an image of an object in an analyzer-based system with a polychromatic x-ray beam from an x-ray source, wherein an analyzer crystal and a detector simultaneously acquire a rocking curve of the x-ray beam for all energies of the x-ray beam. The x-ray beam is diffracted through the object using an asymmetrical monochromator. A detector movement is synchronized with one of the x-ray source or the object. The synchronization includes moving the detector at a first rate that is different than a second rate of the object or the x-ray source, wherein a ratio between the first rate and the second rate is determined by the magnification of the system.
