Coded-Apertures for Depth-Resolved X-ray Laue Microdiffraction

APS Scientific Computation Seminar Series

Abstract: Doga Gursoy will introduce a rapid data acquisition and reconstruction method to image the internal microstructure of crystalline materials using Laue diffraction. Our method relies on scanning a coded aperture across the diffracted x-ray beams from a broadband illumination, and a reconstruction algorithm to resolve Laue patterns as a function of depth along the incident illumination path. This method provides a rapid access to full diffraction information at sub-micrometer volume elements in bulk materials. In this talk, Gursoy will present the underlying theory and the experimental validation, as well as the roadmap for this new imaging approach.
