X-ray fan beam coded aperture transmission and diffraction imaging for fast material analysis

Abstract X-ray transmission imaging has been used in a variety of applications for high-resolution measurements based on shape and density. Similarly, X-ray diffraction (XRD) imaging has been used widely for molecular structure-based identification of materials. Combining these X-ray methods has the...
