Phase retrieval tomography in the presence of noise
journal contribution
posted on 2010-02-01, 00:00 authored by B D Arhatari, Will GatesWill Gates, N Eshtiaghi, A G PeeleWe describe the use of single-plane phase retrieval tomography using a laboratory-based x-ray source, under conditions where the retrieval is not formally valid, to present images of the internal structure of an Aerosil granule and a hydrated bentonite gel. The technique provides phase images for samples that interact weakly with the x-ray beam. As the method is less affected by noise than an alternative two-plane phase retrieval method that is otherwise formally valid, object structure can be observed that would not otherwise be seen. We demonstrate our results for phase imaging in tomographic measurements.
