Summary

This course addresses the principles governing the interactions between light and biological tissue, their optical properties and basic concepts of radiometry. Illustrative diagnostic and therapeutic applications of light in medicine and photobiology will also be described.

Content

Introduction
Brief history
Introduction to general optics and tissue optics
Radiometry and Photometry
Light dosimetry
Light-tissues interactions
Introduction to molecular spectroscopy
Photosensitizers
Principles and techniques
Absorption, fluorescence and vibrational spectroscopies and imaging.
Time-resolved spectroscopy and imaging.
Light sources, detectors and optical systems.
Applications
Analytical techniques, oxymetry, optical biosensors, Photodetection of early cancers with exogenous and endogenous dyes, Angiography, Phototherapy and Photodynamic therapy, optical coherence tomography.

Keywords

Biomedical photonics, tissue optics, light-tissue interactions, photodiagnosis, phototherapy, light dosimetry, dyes, photosensitizers.
