Paper Abstract

TV holography can be used to measure the small variations in refractive index found in acoustic fields in transparent substances. Projections of the amplitude and phase are imaged with an imaging interferometer, and several projections may be combined, using tomographic techniques, to form a volume mapping of the acoustic field. Both projections and reconstructions of acoustic fields in water are presented and discussed. Finally, some of the limitations of this technique are considered.
