General Information

Division: Atomic Physics
Course type: Course given jointly for second and third cycle
The course is also given at second-cycle level with course codes: FAF150, FYST22
Teaching language: English

Aim

The aim with the course is to give the student knowledge of the interaction between light and highly scattering media, such as e.g. tissue. This knowledge is central for a large number of clinical diagnostic tools as well as laser based treatment modalities. Biomedical optics is a fast developing field of research and the medical industry will require people with this knowledge in the near future.

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• be able to explain basic interactions between light and tissue
• be able to explain how optical properties of highly scattering media can be measured
• be able to describe how light propagation in tissue can be simulated
• be able to in depth describe an example of use of optics/lasers ain biomedical applications
• be able to briefly describe other therapeutic and diagnostic medical laser applications
• be able to explain the basic principles for therapeutic and diagnostic applications of lasers in medicine

Competences and Skills

For a passing grade the doctoral student must

• be able to measure optical properties of tissue
• be able to model light propagation in tissue
• have gained competence in composing a report describing an accomplished project, with emphasis on a thorough analysis of published data and own results
• be able to integrate and analyse information from multiple sources

Judgement and Approach

For a passing grade the doctoral student must

• be able to choose and motivate a modelling approach for light propagation in a turbid medium under specific conditions
• be able to choose and motivate a suitable measurement technique to obtain optical properties of tissue depending on tissue type and condition, wavelength and geometry
• be able to evaluate what the critical laser parameters are for a specific medical laser application
• be able to find relevant information on the internet and in libraries
• have gained an interest for challenges in biophotonics and medical laser applications, especially for problems related to light propagation in turbid media.

Instruction Details

Types of instruction: Lectures, seminars, laboratory exercises, project

Examination Details

Examination formats: Written exam, written report, written assignments, seminars given by participants. For grade 3 approved project and exercises are sufficient. The project is performed in groups of two students. The project is presented both orally and as a written report. For higher grades a written examination is required. A well performed project can give bonus points at the first regular examination. The project, two laboratory exercises and three computer exercises are compulsory
Grading scale: Failed, pass
