Description

At Research Center COM we have entered into a collaboration with other DTU institutions (namely Institute of Physics and IMM) and Forskningscenter Risø, concerning biomedical optics (BIOP). The BIOP initiative covers four forcus areas.
At COM we are primarily involved in the development of optical coherence tomography (OCT) systems, and over the past year, we have in collaboration with Forskningscenter Risø developed a theoratical/numerical model describing the noise-properties of practical OCT systems. In addition to this model, which has been used in the design of next generation OCT systems, detailed modelling of light propagation in random media (living tissue such as skin or eyes) has been performed. Results of this work have been presented at international conferences such as Conference on Optical Tomography and Spectroscopy of Tissue, San Jose, CA.
Another key activity for Research Center COM concerning the BIOP collaboration has been the initial investigations of photonic crystal fibres (PCFs) in sensors. Here we make use of the fact that the PCFs contain micron wide holes and provide the possibility for guiding light in these. Hereby, an attractive alternative to evanescent field waveguides becomes possible, and at COM we have applied our detailed numerical tools in describing the waveguideing properties of such new sensor waveguides presented at the International Conference LIGHT FOR LIFE 99 in Cancun, Mexico.
