报告摘要:

 

 The presentation gives an overview of the research activities in Active Imaging Systems which started a decade ago in the N4CI group. This overview first gives a brief outline of the data driven approach in Adaptive Optics when use is made of a Wavefront Sensor. The typical application is in real-time image enhancement for Astronomy. The key contribution presented is that data is used to model the optical aberration dynamics that can then efficiently be used in H2 optimal aberration correction. Continuing on the advantages of the model based approach the aberration modeling is discussed more extensively for confocal microscopy in a sensorless AO set-up. Here the results of efficiently and reliable compensating a single focal point are presented. The framework of research in the N4CI group, i.e. the Smart Optics System Program sponsored by the Dutch National Science Foundation (STW) is also brief outlined during the presentation.

 

 

报告人简介:

 

 Michel Verhaegen received an engineering degree in aeronautics from the Delft University of Technology, Delft, The Netherlands, in 1982 and the doctoral degree in applied sciences from the Catholic University Leuven, Belgium, in 1985. From 1985 to 1994, he was a Research Fellow of the U.S. National Research Council (NRC), affiliated with the NASA Ames Research Center in California, and of the Dutch Academy of Arts and Sciences, affiliated with the Network Theory Group of the Delft University of Technology. From 1994 to 1999, he was an Associate Professor of the Control Laboratory, Delft University of Technology and was appointed as Full Professor with the Faculty of Applied Physics, University of Twente, The Netherlands, in 1999. In 2001, he moved back to the University of Delft and is now a member of the Delft Center for Systems and Control. His main research interest is the interdisciplinary domain of numerical algebra and system theory. In this field he has published over 100 papers. Current activities focus on the transfer of knowledge about new identification, fault tolerant control and data-driven controller design methodologies to industry. Application areas include smart structures, adaptive optics, and vehicle mechatronics.
