An electron microscope has a much higher resolving power than a light microscope but is also much more expensive. Furthermore, it requires special preparation of objects, which makes it impossible to observe living objects. Optical microscopes allow for observing living objects but do not yield the resolution necessary for objects such as nanoparticles, proteins or viruses. The technique of "super-resolving" microscopy helps overcome this limitation and enables observation of viruses interacting with living cells, for example.

This project aims at reconstructing "super-resolved" images from a number of lower-resolved images obtained through an optical microscope. The reconstruction is done in real time using a GPU-based workstation and delivers unprecedented detailedness in space and time. A software package is being developed which enables interaction of the microscope and the computer, implements and optimizes the image reconstruction and allows for viewing and further processing of the images.
