X-Ray Imaging with Ultra-Small-Angle X-Ray Scattering as a Contrast Mechanism



Lyle E. Levine, Gabrielle G. Long


A new transmission X-ray imaging technique based upon ultra-small-angle X-ray scattering (USAXS) is described. Images are formed from angle-filtered X-rays that are scattered by electron density variations within the sample. Stereo USAXS imaging provides three dimensional information on the sizes, shapes, and spatial arrangements of the scattering objects. Remarkably, such information can be extracted even when the scattering objects are smaller than the spatial resolution. In this Letter, USAXS imaging is demonstrated on creep cavities in polycrystalline Cu.
