Paper Abstract

The pressure variations from a sound source lead to corresponding variations in the refractive index which can be measured using TV holography. We measure cross-sections of the integrated sound fields from different directions. To obtain a complete map of the volume distribution of sound field we use tomographical backprojection of these recordings to reconstruct the amplitude and phase of the sound field in any plane of the volume.
