Currently, the autumn school as part of the Special Semester «Tomography Across the Scales» takes places at the RICAM in Linz. Peter Elbau, also one of our project leaders of the SFB «Tomography Across the Scales», was invited to give an introductory lecture on the mathematics behind optical coherence tomography. The audience, including several members of CSC, warmly welcomed the intuitive and very well presented lecture on this highly complex topic.
