We can slice it. We can dice it. We can study it (even easier than before). Using 3D imaging, NIST researchers can digitally represent objects and mathematically manipulate them without damaging or altering the physical object. Being able to see an object in 3D, inside and out, means that we can better understand it. For example, we use techniques such as x-ray computed tomography (XCT) to explore microscopic particles in lunar soil, solder bumps in integrated circuits, foam used in helmets and
