Research Grant

Researchers: A/Prof Leslie Allen (Chief Investigator)

Brief description The phase and inverse scattering problem for electrons multiply scattered by non-periodic solids. Theoretical methods for the inversion of multiple scattering of electrons in non-periodic solids will be obtained. This will vastly extend the range of utility of atomic resolution electron microscopy and electron tomography, where single scattering conditions are usually assumed. We will further develop our recent novel solutions to the phase problem from images and diffraction patterns (needed as a prelude to the inversion) that are robust in the presence of discontinuities in the phase (such as vortices). These phase retrieval methods will be useful not only for problems in electron optics but also in visible, x-ray, neutron and atom optics.
