Biomedical Optics

Biomedical optics include optical technology and applications in biomedical research and medicine. With the development of new laser technology, fibre optics, opto-electrical equipment, biosensors, spectroscopy, microscopy, and imaging, this discipline is growing rapidly. The new technology provides a foundation for new applications in medical research, diagnosis, and treatment.

In the strategic area of medical technology, a network in biomedical optics has been created to stimulate and promote collaboration between researcher groups at NTNU, SINTEF and St.Olavs Hospital.


Active research groups at NTNU are mainly at the Faculty of Natural Sciences and Technology, the Faculty of Information Technology, Mathematics and Electrical Engineering, and the Faculty of Medicine.

The Faculty of Medicine and the Faculty of Natural Sciences and Technology are active in optical imaging based on confocal and multi-photon laser scanning microscopy. Together, they have established the node "Subcellular Interactions and Imaging" in the Norwegian Molecular Imaging consortium (NorMIC)". This node is one of the technology platforms in the research programme Functional Genomics (FUGE II).

The Faculty of Natural Sciences and Technology, Department of Physics conducts research in spectroscopy, fluorescence correlation spectroscopy, confocal and multi-photon laser scanning microscopy, non-linear optics, photobiophysics, biophysics of vision , photodynamic therapy, transport of therapeutic macromolecules in tumour tissue and cardiovascular diagnosis using multi-photon microscopy.

The Department of Electronics and Telecommunications at the Faculty of Information Technology, Mathematics and Electrical Engineering is home to research in several areas of biomedical optics, including optical dosimetry, tissue characterization and optical diagnostics.

An important area of focus for the department has been optical diagnostics and modelling of skin haemorrhages, as well as optical diagnostics in connection with laser therapy. Another activity involves the development of sensor technology for biological applications, including detection of atherosclerotic plaque. Researchers at the department are also exploring fibre-optic sensors, optical medical imaging techniques and image analysis (primarily hyperspectral imaging), as well as reflection and absorption spectroscopy.

The Department of Cancer Research and Molecular Medicine at the Faculty of Medicine is conducting research on photodynamic therapy. Fluorescence correlation spectroscopy and confocal laser scanning microscopy are central tools in the research.


  • The Department of Physics offers courses in optics, photobiophysics, biophysical micromethods
  • The Department of Biology offers a course called Bio-Visualization
  • The Department of Electronics and Telecommunications teaches courses in general electrooptics and applied phototonics, as well as in medical sensors.
