Biophotonics Laboratory

Head of laboratory – prof. Jānis Spīgulis

Main directions of scientific work:

Development of optical methods and devices for medical and technological applications.

• early non-invasive skin cancer diagnostics and classification of skin lesions using multispectral diffuse reflectance and autofluorescence imaging techniques combined with artificial neural network analysis;
• early detection of sepsis on the knees using multispectral imaging techniques;
• contactless photoplethysmography imaging to monitor the time of exposure to anesthesia;
• assessment and presentation of oxygen saturation in the skin;
• laser beam contrast imaging for microbial growth analysis;
• time-resolved diffuse reflectance and in vivo skin autofluorescence using time-dependent single-photon counting;
• detection of counterfeit currency by multispectral imaging techniques.
