Location：Second meeting room of Research Building 

Abstarct：Research of optical imaging is still very much alive.  We review vectorial imaging theory of high NA systems and the link that exists between vectorial point spread functions and fields in image space with maximum electric field components. Then we consider SLMs to shape scanning focal spots in an optimum way and we discuss coherent scatter ometry applied to sub wavelength structures. We show that computation imaging can be applied to both object and aberration retrieval at the same time. If time permits, we will also briefly mention hyperbolic media as a method to achieve super-resolution.

CV: Prof. H.Paul.Urbach has a PhD from the University of Groningen. Until 2008 he was a principal scientist at Philips Research Laboratories in Eindhoven. In 2000 he became part-time professor Diffraction Optics in the Optics Resarch Group of TUD and in 2008 he became leader of this group. He is Member of the International Commission of Optics, immediate Past President of the European Optical Society, Member of the Dutch URSI committee, Member of the Advisory Committee of the Dutch Government on Metrology.
