Physical Optics and Biophotonics Group
Institute of Physical Chemistry PAS


The research in our group can be seen as a perfect interplay between physics, biology and chemistry. We are focusing on developing imaging techniques and using them in many biological and chemical systems. Uniqueness of our approach is using not only amplitude of the light, but also its phase in order to develop new, top class imaging systems. Optical Coherence Tomography is the great example of such method (see movie below of long-range OCT volume of human eye). Furthermore, we are implementing the innovative method for imaging distortion removal ― STOC (Spatio Temporal Optical Coherence manipulation), that have a potential to largely increase the quality of imaging through opaque layers, such as skin.

All these projects are aimed to bring to humanity a new non-invasive imaging techniques, that will make our life longer, better and with more understanding of the nature.

Principal Investigator

Prof. Maciej Wojtkowski is a renowned scientist active in the field of biomedical imaging. His research interests include optical coherence imaging and microscopy applied to biomedical imaging. He has a pioneering contribution to design and development of ultra-high speed Optical Coherence Tomography (OCT), which is commonly used in ophthalmic and cardiologic diagnosis. Multiple OCT prototypes developed by Prof. Wojtkowski served as the basis for many instruments in ophthalmology clinics across the World.

Maciej Wojtkowski authored more than 160 publications, including 90 full papers in peer reviewed journals (Google Scholar and Research Gate). During his academic career Maciej Wojtkowski gained international experience, while working at the Massachusetts Institute of Technology, Cambridge, MA (USA) and New England Eye Center, Boston, MA (USA). He was also on research internships in Vienna University and University of Kent.

Currently, he is the Head of the Department of Physical Chemistry of Biological Systems at the Institute of Physical Chemistry of Polish Academy of Sciences. He won the international competition for the ERA Chair holder in the CREATE project (EU HORIZON 2020).
