acoustic tomography

acoustic tomography

[ə′küs·tik tə′mäg·rə·fē]
(acoustics)
An imaging or remote sensing technique in which information is collected from beams of acoustic radiation which have passed through an object, generally in the form of an image or other representation of a two-dimensional slice through the object.

OceanObs'99 identified high-latitude regions and the Arctic Ocean as key areas where ocean acoustic tomography should be applied (Global Ocean Observing System Steering Committee, 2000; IOC, 2000; Dushaw et al., 2001).

Recent methods aimed at improving the accuracy of the source location technique by alleviating the problems inherent in selection of a single wave velocity include modal analysis, a method based on energy attenuation and acoustic tomography.
Several of these techniques include ultrasonic flaw detection and scanning acoustic microscopy (SAM), sometimes called scanning acoustic tomography. SAM generates a 3-D image of the internal solid interface structure of the part inspected.
Because the upper ocean layer is so quiet, scientists won't be able to use "acoustic tomography' to study its dynamics during an El Nino.

It has been noted that visual inspection and single-path stress wave tests can identify a general problem; acoustic tomography reveals the general location and magnitude of a defect within the cross section tested; and resistance micro-drilling precisely locates defects and differentiates between decay and crack-induced acoustic shadows.
It is further shown that the AETOMO approach offers totally new perspectives, not only for AE imaging but also for traditional acoustic tomography since AE events can also be produced artificially at the outer surfaces of the specimen under investigation (e.g.
