Diploma projects

In the Applied molecular spectroscopy and remote sensing group we are always interested in students who want to perform their diploma projects (master's thesis, master project, etc.) in an applied and broad field of physics.

You have the possibility to do a project within any of the suggested areas below and if you have any other suggestion or questions, don't hesitate to come and discuss with us!

If you are interested in performing your project in our group, please contact Sune Svanberg, Mikkel Brydegaard or Patrik Lundin. Contact information is found under "The Group".



Sensing of CO2 in scattering media

The technique GASMAS is used to study gases situated inside scattering media. The technique has been used at the Atomic Physics Division for studies of human sinus cavities, lungs, wood, fruit, food packages, etc. The two gases mainly studied so far are oxygen and water vapor. Recently, a project where the technique is to be used to study also CO2 was started. The project will consist of one part aiming to study CO2 content in food packages since much food today is stored in so called modified atmospheres, sometimes containing CO2. CO2 is a gas closely related to biological activities which thus can be studied. Another part of the project is, in a way, more fundamental, dealing with how the CO2 behaves in materials with extremely small pores. Very fundamental physical phenomena such as wall collision broadening and pressure broadening are encountered. The thesis can deal with both parts or one of them. Contact:


Studies of archaeological wood (related to VASA)

The Atomic Physics Division has is collaborating with an Italian group to study archaeological wood with the help of Time-Of-Flight spectroscopy and GASMAS. Studies of ancient wood is a large research area dealing with how different chemical and physical processes affect the aging of for example shipwrecks and old wooden buildings. Our specific project deals with how optical techniques can assist in the research of wood. The work in Lund is mainly concerned with how gases diffuse in and out of wood, how oxygen is consumed by aging wood, how different wood materials respond differently to light and how all these aspects affect the aging of wood. This project is a collaboration with the VASA museum in Stockholm and actual pieces of the Swedish warships VASA and Riksäpplet are studied.


Multispectral sensing towards medicine and ecology

In the Applied Molecular Spectroscopy and Remote Sensing  Group much work has recently been done on how multispectral imaging can be used to study ecological systems like insects and birds remotely. Another aspect has been multispectral microscopic studies of  malaria and other diseases. The latter project is a collaboration with developing countries. An African network for solving important problems by spectroscopic technique has been formed. The diploma work consists in developing multi-spectral imaging techniques based on LEDs and to apply advanced image processing techniques to extract information. The diploma project culminates in participation as instructor in a two-week workshop in Nairobi, Kenya, August 2012, together with researchers from Kenya, Ghana, Ivory Coast, Burkina Faso, Senegal, Mali and Sri Lanka.


Development of sensitive gas analysis using correlation techniques

Industrial applications require robust and realistic sensor techniques. The Applied Molecular Spectroscopy and Remote Sensing group has been very active it the development of such methods. The present diploma project regards applications of multi-mode diode lasers combined with gas correlation spectroscopic techniques, where the requirements on the spectroscopic components are relaxed, since the spectrum of the gas of interest provides the internally calibrated reference. Higher detection sensitivity can be achieved by using frequency-modulation and prolonged path-length techniques.
