"Light Scattering: Simulation and inversion"

University of Bremen, Bremen, 27. + 28. May 2013


At the heart of many modern industrial applications is fast and accurate numerical solution of inverse light scattering problems. For example, in metrology inverse scattering techniques are used in applications ranging from the small-scale optical characterisation of micro- and nanostructures to large-scale radar imaging.

Light scattering more and more becomes an indispensible tool in this context. Particle surface contaminations have to be detected, sized and characterized. For aerosol characterization spectroscopic methods and Lidar are used. Soot aggregates in an industrial or environmental setting have to be characterized based on measured scattering characteristics.

A common challenge for inverse problems in applications is the need for a thorough theoretical understanding of the problem and the difficulties, as well as fast and reliable numerical algorithms for inversion. The aim of this workshop is to bring together researchers working on different aspects of light scattering and inverse problems from theory to computations and real-life applications.
