 Subject:  MODULE C: Course on Optical Sectioning and 3D reconstruction

The module has been designed to teach fundaments of optical sectioning and 3D reconstruction from ultra-structure to function. Microscope components that allow optical sectioning and concepts such as structured illumination and channels will be explained as well as going deeper into image analysis.T

Talks will describe the various approaches for obtaining optical sections in the range of cellular dimensions. Hardware and software solutions will be presented. Principles of optical sectioning have been discussed in previous Modules in details and will be briefly summarized. Participants are invited to revisit the didactic material of Module A and B.
