Abstract:
There exist various techniques to “scan” an object using x-rays, the most common of which uses a polar sampling grid, all relying on the diffraction equation known as Bragg’s Law [1, 6]. During my internship at Oak Ridge National Laboratory, I investigated the uses and efficiency of application of two specific types of grids: a hexagonal grid and a spiral grid, details of which are given below. The hexagonal [2, 3, 4] and spiral [5] methods have been introduced and used previously, without including the mathematical details necessary to actually implement these methods. I developed the algorithms necessary to generate each grid and implemented them (by writing computer code) to test my results.
