Abstract

Understanding the material composition everywhere in a three-dimensional volume is important for medical, security, and material science applications. Using a fan beam geometry with detector-side coded aperture, we demonstrate fast, high-resolution 3D X-ray diffraction (XRD) imaging. The XRD imaging system has a 15 x 15 cm2 field of view with a spatial resolution of approximately 1x1.5x7 mm3 (width x length x depth), a fractional momentum transfer resolution of approximately 10%, and scan times on the order of 10 minutes. Using this system, we show the ability to differentiate between two similar-density organic materials (water and PLA) in 3D using conventional, off-The-shelf components.
