Atkinson, K M, Sweeney, Francis and Rodenburg, J M (2010) Solving for the phase of STEM probes in real space. Journal of Physics: Conference Series, 241 (1). 012064. ISSN 1742-6596

The combination of a Gerchberg-Saxton phase retrieval algorithm with a genetic algorithm is used to retrieve the phase of a TEM or STEM probe and pinpoint its defocus. Results from modelled data and initial experimental work are included.
