Biophotonic Technologies

Tuesday, May 3, 2016 to Wednesday, May 4, 2016


Infotech Oulu Doctoral Program

Lecturer: Professor Janis Spigulis, Physics Department of University of Latvia (UL), Head of Biophotonics Laboratory at the Institute of Atomic Physics and Spectroscopy, UL

Date & time:

May 3, 2016 (Tuesday), 9-14
May 4, 2016 (Wednesday), 9-15

Room: TS267 (Tietotalo 1)

The first part of the course describes the fundamentals of biophotonics, including the basic principles, photonic components (light sources, photodetectors, lightguides, image sensors) and systems. It will be followed by basic tissue optics and review of laser-tissue interactions. Specific methods for optical diagnostics and monitoring of living tissues (absorption spectroscopy, diffuse reflection spectroscopy, fluorescence, multispectral imaging, contact and remote photoplethysmography, laser Doppler flowmetry, optical tomography) will be discussed in the first part of the course, as well.

The second part of the course will focus on clinical applications of the above-regarded principles and methods. It will be divided into three main topics:

  • laser surgery (eye surgery, vascular surgery, cosmetic applications)
  • optical diagnostics (reflectance, fluorescence, multi-spectral imaging, OCT)
  • optical monitoring (pulse oximetry, photoplethysmography imaging, laser-Doppler imaging).

Besides, the main aspects of clinical laser safety will be discussed.

The third part of the course will cover the biophotonic technologies and devices developed at the Biophotonics Laboratory in Riga over the recent decade. The main focus will be on low-cost equipment for in vivo skin diagnostics and monitoring, including that for skin cancer detection and for remote monitoring of anesthesia during surgeries.
