10:00h Tour Fraunhofer IOSB (optional)

12:00h Registration and Snack

13:00h Welcome and Opening

13:10h Keynote Speech (Prof. Dr. Rudolf Kessler):

  • Sensitivity and Selectivity in Optical Spectroscopy and Imaging:  
    A Molecular Approach

    Prof. Kessler will open the conference with a speech about the advantages and disadvantages of different techniques in optical spectroscopy. Optical spectroscopy will play a major role in the sensor technology as it provides simultaneously chemical and morphological information. Sensitivity and selectivity are important features for the use of spectroscopy in sensor applications.
