Bio-aerosol detection
  KTH Applied Physics seminars

Thursday 28 February 2013
from 09:00 to 10:00
at FA31
Speaker : Per Jonsson (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.
