| Zusammenfassung | An introduction is given to the principles of acousto-optical interaction in fluids by means of the Schlieren technique, light diffraction and interferometry. The usefulness of these techniques for the investigation of ultrasonic fields is discussed. Particular emphasis is placed on selected applications for quantitative field mapping with high spatial and temporal resolution. These applications involve non-invasive measuring techniques as, for instance, light-diffraction tomography for sound field investigations in water in the MHz frequency range and laser interferometry for sound field investigations in air in the low ultrasonic frequency range. A special section deals with recent sensor developments based on an optical dielectric multilayer system. |
