From Tomographic Phase Retrieval to Projection Tomography - IPAM at UCLA

Explore a 45-minute lecture on advanced imaging techniques presented by Albert Fannjiang from the University of California, Davis. Delve into the analysis of measurement schemes that enable the reduction of 3D unwrapped phase retrieval to projection tomography, with a focus on the crucial role of coded apertures. Discover how this approach aims to apply successful projection-based techniques from cryo-EM to process diffraction data under challenging conditions, including sample heterogeneities and unknown orientations. Examine the use of beam splitters and various tilt schemes to achieve data reducibility, and learn about solutions to the phase unwrapping problem in 3D projection tomography. Gain insights into cutting-edge methods that bridge the gap between tomographic phase retrieval and projection tomography, advancing the field of diffractive imaging.
