X-ray absorption tomography employing a conical shell beam.
We demonstrate depth-resolved absorption imaging by scanning an object through a conical shell of X-rays. We measure ring shaped projections and apply tomosynthesis to extract optical sections at different axial focal plane positions. Three-dimensional objects have been imaged to validate our theoretical treatment. The novel principle of our method is scalable with respect to both scan size and...
متن کاملX-ray absorption and diffraction studies
We have produced assemblies of FePt nanoparticles using high temperature solution phase synthesis and polymer-mediated layer-by-layer deposition allowing precise control of the particle self-assembly. The as-deposited particles have a narrow size distribution offering the potential for use as ultra-high density magnetic storage media and ultimately storage of one bit per individual nanoparticle...
متن کاملTriplet-phase measurements using reference-beam X-ray diffraction.
Reference-beam diffraction (RBD) is a recently developed phase-sensitive X-ray diffraction technique that incorporates the principle of multiple-beam diffraction into the standard oscillating-crystal data-collection method [Shen (1998). Phys. Rev. Lett. 80, 3268-3271]. Using this technique, a large number of multiple-beam interference profiles can be recorded simultaneously on an area detector,...
متن کاملSolving the Phase Problem Using Reference-Beam X-Ray Diffraction
A new method of obtaining Bragg reflection phases in an x-ray diffraction experiment is presented. It combines the phase-sensitive principles of multiple-beam diffraction and x-ray standing waves, and allows direct phase measurements of many multiple reflections simultaneously using a Bragg-inclined oscillating-crystal geometry. A modified-two-beam intensity function is devised to extract the p...
متن کاملEnergy-dispersive X-ray diffraction using an annular beam.
We demonstrate material phase identification by measuring polychromatic diffraction spots from samples at least 20 mm in diameter and up to 10 mm thick with an energy resolving point detector. Within our method an annular X-ray beam in the form of a conical shell is incident with its symmetry axis normal to an extended polycrystalline sample. The detector is configured to receive diffracted flu...
