A computer simulation of acoustical image reconstruction

The Journal of the Acoustical Society of America, 1983
Acoustical holographic reconstruction techniques which were developed by Williams et al. [J. Acoust. Soc. Am. 68, 340–344 (1980)] have been simulated on a digital computer. Sound pressure and normal acoustic intensity images are reconstructed and graphically compared with their theoretical values for simple monopole and dual monopole configurations ...

Method and apparatus for reconstructing and acoustic field

The Journal of the Acoustical Society of America, 2004
Acoustic field reconstruction is performed by expanding basis function which represent outgoing and incoming waves, without prior knowledge of the source geometry and dimensions. The reconstruction is based on acoustic pressures measured in the field only, and can be accomplished on a piece-wise basis.

Reconstruction of Clipped Waveforms in Acoustic Emissions

Geophysical Prospecting
ABSTRACT Acoustic emission (AE) is elastic waves generated spontaneously from the creation of micro‐cracks. AE waveforms share significant similarities with microseismic signals and serve as an effective tool for improving the understanding of fracture processes during hydraulic fracturing.

Reconstruction of Fluid Vorticity by Acoustic Tomography

1992
A new procedure for reconstructing fluid vorticity by acoustic tomography is developed. We consider a hypothetical experiment where a cross-section of moving fluid is probed by acoustic waves. The measured propagation times are then related to the fluid vorticity by means of a new Projection-Slice Theorem.

Acoustical Reconstruction of Holograms, and Their Potential Use

1972
Extensive work has been performed to date in coherent optical processing. Coherent acoustic processing, on the other hand, has not progressed as far as its coherent optics counterpart, although it has identical operational capabilities. Some progress had been reported earlier1 in the development of acoustical holographic matched filters, but the ...
