Mathematics in Imaging
24 June 2019 – 27 June 2019 Messe München, Munich, Germany
This meeting is an opportunity to gather people from optics, mathematics, and signal processing to cross-fertilize these fields with discussions on novel technologies, methodologies and challenges.
Communications that are not directly related to imaging, but could be of interest to the field or unsolved challenges in optics, requiring advanced signal processing tools are particularly welcome.
Topics
1. Foundations in electromagnetics and imaging
- Propagation of waves
- Scattering (e.g. surface scattering, volumetric scattering)
- Phase, statistical optics, coherence optics
- Image formation (e.g. tomography, telescope, microscopy, remote sensing,
multi-aperture system) - Theory and algorithms of optical element designs (e.g. computer generated hologram,
volume holograms, photonic elements) - Nonlinear optics
- Linear and nonlinear spectroscopy
2. Foundations in mathematics and signal processing
- Variational or Bayesian regularization of inverse problems (e.g. total variation or frame
based regularization) - Bilinear inverse problems (e.g. blind deblurring, self-calibration)
- Sampling theory (e.g. compressive imaging, adaptive sampling)
- Theory and algorithms of learning techniques (e.g. dictionary learning, neural networks)
- Optimization theory and algorithms for convex and nonconvex problems (e.g. phase
retrieval, inversion of multiple scattering)

The Ongoing Adaptive Optics Revolution
Adaptive Optics enhances the performance of imaging systems down to the diffraction limit and more in general can flatten the wavefronts in optical systems in real time. It is a technology now increasingly used in astrophysics, ophthalmology, microscopy, beam shaping of high power lasers for industry, beam pre-shaping for large baseline interferometry, precision microelectronics fabrication, satellite free space optical communications, quantum computing, to name a few. Adaptive Optics technologies are very lively transforming and on the move.
We will review together the status of Adaptive Optics Technologies. Some of the most beautiful technological and application achievements will be shown, including recent developments obtained observing our Universe, with novel Laser Guide Star Adaptive Optics installations at the largest, more remote astrophysical observatories in the world.
About the Speaker
Domenico Bonaccini Calia has been working as a physicist at the European Southern Observatory (www.eso.org) for over 24 years, where he currently has an international member staff position.
He obtained his Masters in physics at the University of Florence, Italy, then completed a PhD in astrophysics, and a postdoc period at the Sac Peak National Solar Observatory in New Mexico, USA. On his return to Italy, Domenico held for 8 years a staff position at the Arcetri Astrophysical Observatory, in Florence, where he formed the adaptive optics group in 1990, before moving to ESO, Germany, in 1995.
At ESO he worked in the adaptive optics group and in 2000 he has formed the Laser Guide Star Systems Department, serving as Head of Department until 2010. He has contributed to two laser guide star facilities now installed on the ESO Very Large Telescopes in Chile, is supporting the ESO ELT activities for the new design of its six laser guide star units, and is currently responsible for the laser guide star systems research and development activities at ESO, under the Technology Development program.
D. Bonaccini Calia received the innovation award from the german Leibinger Stiftung in 2016, became a Fellow of The Optical Society in 2018 for its contribution to the progress of photonics in astronomical instrumentation, shared the 2018 Paul F. Forman Team Engineering Excellence Award and as been inventor in 4 different patents related to wavefront correctors and novel laser systems.

Robot learning from Human Guidance
As a fundamental cornerstone in the development of intelligent robotic assistants, the research community on robot learning has addressed autonomous motor skill learning and control in complex task scenarios. Imitation learning provides an efficient way to learn new skills through human guidance, which can reduce time and cost to program the robot. Robot learning architectures can provide a comprehensive framework for learning, recognition and reproduction of whole body motions.
About the Speaker
Dongheui Lee is Associate Professor of Human-centered Assistive Robotics at the TUM Department of Electrical and Computer Engineering. She is also director of a Human-centered assistive robotics group at the German Aerospace Center (DLR). Her research interests include human motion understanding, human robot interaction, machine learning in robotics, and assistive robotics.
Previously, she was an Assistant Professor at TUM (2009-2017), Project Assistant Professor at the University of Tokyo (2007-2009), and a research scientist at the Korea Institute of Science and Technology (KIST) (2001-2004). She obtained a PhD degree from the department of Mechano-Informatics, University of Tokyo, Japan in 2007. She was awarded a Carl von Linde Fellowship at the TUM Institute for Advanced Study (2011) and a Helmholtz professorship prize (2015).
