Abstract:
X-ray scattering imaging can provide complementary information about the unresolved microstructures of a sample. The scattering signal can be accessed with various methods based on coherent illumination, which span from self-imaging to speckle scanning. The directional sensitivity of the existing methods is limited to a few directions on the imaging plane and it requires the scanning of the optical components, or the rotation of either the sample or the imaging setup, if the full range of possible scattering directions is desired. A new arrangement is provided that allows the simultaneous acquisition of the scattering images in all possible directions in a single shot. This is achieved by a specialized phase grating and a device for recording the generated interference fringe with sufficient spatial resolution. The technique decouples the sample dark-field signal with the sample orientation, which can be crucial for medical and industrial applications.

Claim (Index 12):
A configuration for obtaining quantitative x-ray images from a sample, the configuration comprising:\n an X-ray source outputting x-rays; a position-sensitive detector with spatially modulated detection sensitivity having a number of individual pixels; a recorder for recording the x-ray images of said position-sensitive detector; a processor for evaluating intensities in a single shot image for obtaining characteristics of the sample including absorption, differential phase contrast and directional, small-angle scattering contrast, for specified regions of the pixels; an optional absorption grating in front of, or embedded into said X-ray source; and a phase-shift periodic structure being:\n i) a 2D periodic structure composed of unit cells, said unit cells being circular gratings, a period of said unit cells is P and that of said circular gratings is p, wherein periodic structures in a circular grating generate a considerable X-ray phase shift difference, which is of \u03c0/2 or odd multiples thereof, hereinafter referred to as \u03c0/2 shift; or \u03c0 or \u03c0+N\u00d72\u00d7\u03c0, hereinafter referred to as \u03c0 shift, where N is an integer number; or \n ii) a honeycomb structure composed of unit cells, each unit cell is a circular grating which allows a maximum filling factor of such a periodic structure; periodic structures in said circular grating generate a considerable X-ray phase shift difference, which is of \u03c0/2 or odd multiples thereof, hereinafter referred to as \u03c0/2 shift; or \u03c0 or \u03c0+N\u00d72\u00d7\u03c0, hereinafter referred to as \u03c0 shift, where N is an integer number.
