Dr. Per Jonsson, FOI

Abstract:
The seminar will start with a short presentation of FOI – Swedish Defence Research Agency and the research at the Laser systems group. The rest of the seminar will focus on different aspects of biological warfare agent (BWA) detection. Hazardous levels of BWA are difficult to detect since very low doses of the agents can cause disease for humans. To achieve an overall quick and secure response time, many BWA detection systems are based on an initial trigger/warning detector that continuously monitor some inherent property of the aerosol particles. Several techniques, such as elastic scattering, flame spectroscopy, laser-induced breakdown spectroscopy, Raman spectroscopy could be used for this purpose. FOI has mainly investigated ultraviolet laser-induced fluorescence both for point (local) and standoff (results) detection and the development, tests and results of several systems will be presented.


CV:
Per Jonsson received his Ph.D. in Photonics from KTH in 2002. The title of his thesis is “Generation, Detection and Application of Single Photons”. Dr. Jonsson joined FOI – Swedish Defence Research Agency in 2002. His main research area at FOI has been detection of aerosolized biological warfare agents based on ultraviolet laser induced fluorescence, but he has also investigated other technologies for biological and chemical detection. He has also work on free-optical communication, including so called quantum cryptography, and different application of single-photon detection.
