X-ray
phase contrast imaging measures not just the number of X-ray photons that get through the sample, as in conventional X-ray imaging, but also the phase of the X-rays after they pass through, offering a complete look at interfaces inside a structure.
So Sandia borrowed and refined a technique being studied by the medical field, X-ray
phase contrast imaging, to look inside the softer side of things without taking them apart.
Sandia Labs» research began with a Laboratory Directed Research and Development project from 2014 - 2016 that demonstrated X-ray
phase contrast imaging could show details where one material meets another.
X-ray
phase contrast imaging could be used to inspect microfabrication packaging, integrated circuits or micro-electro-mechanical components and could be used to study ceramics, polymers, chemicals or explosives.

phase contrast imaging in a lab without a synchrotron, an expensive piece of equipment the size of a football field.
«Studying the formation and evolution of jets in metals and, more generally, how materials at extreme conditions respond using X-ray
phase contrast imaging is relevant to such things as meteorite impacts, the performance of explosives and detonators, understanding crack nucleation and propagation in materials, and the development of new materials with tailored properties whose applications include automotive and airplane components, lighter and more impact - resistant armor, and debris shields in space, to name a few.»
