MACSI & INVERSE PROBLEMS AND IMAGING GROUP at the department of Mathematics and Statistics at the University of Limerick invites you to a seminar
Speaker: Dr. Andy Stewart (Department of Physics & Bernal Institute, University of Limerick).
Time and location: Friday 21st September, at 4.15 p.m. in Room A2-002
Title: Reconstruction algorithms for transmission electron microscope data.
Abstract: Transmission electron microscope (TEM) data is not directly interpretable, because it has a non-linear relationship with the scattering from the object. A number of different approaches and algorithms are used to reconstruct both imaging and diffraction data to overcome the dynamical scattering problem, improve the resolution achievable and low the radiation dose the specimen receives.
I will present iterative reconstruction algorithms used to recover the average crystal structure form diffraction data. Ptychography which is used to improve resolution and lower dose to the specimen. As well as introduce initial results from compressed sensing reconstruction experiments.
Supported by Science Foundation Ireland funding, MACSI - the Mathematics Applications Consortium for Science and Industry (www.macsi.ul.ie), centred at the University of Limerick, is dedicated to the mathematical modelling and solution of problems which arise in science, engineering and industry in Ireland.
