1. In a method for detecting an image of an object, wherein an x-ray beam is generated, the improvement comprising:

  • transmitting the x-ray beam through the object and emitting from the object a transmitted beam;

    directing the transmitted beam at an angle of incidence upon a crystal analyzer;

    detecting a first image of the object from a diffracted beam emitted from the crystal analyzer at a low rocking curve angle setting of the crystal analyzer;

    detecting a second image of the object from a diffracted beam emitted from the crystal analyzer at a high rocking curve angle setting of the crystal analyzer; and

    combining the first image and the second image to derive a refraction image and an absolute absorption image of the object.
