In many ultrasound applications––especially in the area of medical diagnostics––conventional sensors and particularly piezoelectric hydrophones do not comply with the requirements for “point detectors”. It therefore suggests itself to dev

The correction of the averaging effect of finite-size hydrophones is at present realized by various methods which are based on idealized models for the sound field and thus are valid only to a limited extent. In the present article three methods for

In various fields of ultrasound applications, frequencies well above 10 MHz are used. As a consequence of this, ultrasound sensors, especially the piezoelectric hydrophones presently available which are used for the characterization of the respective

Weak acousto-optical interaction provided, light diffraction tomography has proved to be a useful tool for mapping ultrasonic fields. Beyond this range, data acquisition and evaluation is far more difficult, which is mainly due to the fact that, in t

Ultrasound light diffraction in conjunction with a computer-tomographic evaluation procedure allows ultrasonic fields to be mapped as long as the limits of weak acousto-optic interaction are not exceeded. Beyond these limits, the light-sound interact

For weak and strong acousto-optic interaction analytical solutions are available which describe the diffraction problem. In the intermediate range between these limiting cases, however, the light-sound interaction is far more difficult to analyze for

Light diffraction by ultrasound waves is discussed over the wide range from weak acousto-optic interaction to strong acousto-optic interaction, in terms of numerical simulations and experimental investigations for normal incidence. Particular emphasi
