High-Resolution Three-Dimensional Imaging via X-Ray Reflectometry and Phase-Contrast Computed Tomography

Jefferson Cuadra | 19-ERD-022

Executive Summary

We will develop a method for producing high-resolution measurements of surface topography and density variations in low-x-ray-absorptive materials by integrating two imaging techniques, x-ray reflectometry and holotomography, with reconstruction algorithms. If successful, this method will advance the field of metrology by exploiting nontraditional x-ray physics to achieve three-dimensional imaging at submicron- and nanometer-scale resolutions for applications in advanced materials and manufacturing.
