With background in atomic
spectroscopy, optoelectronics and fibre optics, over the last decade I am
mostly involved in biophotonics research. We develop novel optical methods and devices for non-invasive diagnostics and monitoring
of human health condition. Spectral, temporal and imaging analysis of
optical signals from in-vivo skin may ensure quantitave assessment of
cardio-vascular state, skin blood micro-circulation, skin pigmentation and
various skin malformations. The techniques developed in laboratory and
evaluated in clinical studies are photoplethysmography (PPG), fluorescence,
diffuse reflectance spectroscopy and multi-spectral imaging. The expected
outcomes of our research are advanced clinical technologies, such as:
ü Fast
detection of leg stenosis by bilateral PPG;
ü Remote
cardiovascular monitoring by embedded wireless PPG sensors;
ü Remote
skin blood perfusion control during anaesthesia by PPG imaging;
ü Remote
skin chromophore mapping by multi-spectral imaging analysis;
ü Remote
skin melanoma detection by chromophore correlation analysis;
ü Improved
skin laser safety standards with respect to skin “photo-memory” at
low power irradiation.
