Photoacoustic Effect Principles and Applications: Proceedings of the First International Conference on the Photoacoustic Effect in Germany

VI The idea to hold such a meeting in Germany for the first time was due to Prof. H. Pelzl. Its realization was greatly supported by financial help of the Stiftung Volkswagenwerk and the Deutsche Physikalische Gesellschaft, which is gratefully acknowledged. The Editors VII Contents 1.
