General course objectives:

The interest for applications of coherent light and optical sensing in biology and medicine has been increasing the past years. This is partly due to the development of new laser systems, parly the development in integrated optical sensors and advances in precise and non-invasive diagnostics and analysis of biological and medical processes. The course is divided into three arears: 1. New light sources for medical diagnostics and treatment, 2. Optical techniques for image formation in human tissue, 3. Optical biosensors.

Learning objectives:

A student who has met the objectives of the course will be able to:
  • Discuss simple optical principles like coherence, interference and diffraction, and determine imaging properties of simple rays in spherical lenses and mirrors.
  • Explain the principle of laser action and understand the mode of operation of the various components in different laser systems.
  • Discuss the physics behind nonlinear frequency conversion, and describe tuning properties of coherent light sources based on nonlinear frequency conversion.
  • Explain different light tissue interactions, e.g.: Photochemical, thermal, photo induced plasma and photo ablation, and be able to relate these interactions to the characteristics of the light source.
  • Discuss the optical properties of tissue (scattering and absorption) and the wavelength dependencies of these processes.
  • Describe the principle of transport theory and knowledge of solutions, including diffusion theory.
  • Apply the principle of Monte Carlo simulations as a general solution and understand how this method can be used to solve transport theory of light propagation in scattering media.
  • Explain and discuss the functionality of a specific optically based diagnostic system, OCT.
  • Describe spectroscopic techniques such as fluorescence and Raman spectroscopy, and understand the functionality and limitations of a spectrometer, e.g. detector sensitivity and noise.
  • Do simple exercises within the topics covered in the lectures and discuss the obtained results both orally and in writing.

Content:

The lectures will cover the biological and medical background for application of light for treatment and diagnosis, especially propagation of light in humane tissue, interaction between light and tissue, possibilities for therapy with light and imaging methods and image analysis. Another important topic is the optical properties of the eye: Spectral properties, fluorescence of the various parts of the eye, optical diagnostics by scattered light within the eye, properties of the retina and possibilities for healing by optical treatment. Further, modern coherent light sources will be covered such as the optical properties of laser beams, different laser systems and their potential for bio-medical applications. Throughout the course practical examples and demonstrations will be used whenever possible.

Remarks:

Lectures from DTU Photonics Engineering, and a number of invited external lectures.

Green challenge participation:

Please contact the teacher for information on whether this course gives the student the opportunity to prepare a project that may participate in DTU´s Study Conference on sustainability, climate technology, and the environment (GRØN DYST). More infor http://www.groendyst.dtu.dk/english
