During acoustic imaging
, the spaces between the cracks helped to reflect ultrasound and create the anomaly seen in Figure 1.
By placing the metamaterial between the imaging device and the object being imaged, we were able to more than double the resolution of the acoustic imaging
-- from one-half the sound's wavelength to greater than one-fifth.
These constraints make acoustic imaging
of MLCCs after reflow or wave soldering an important tool.
has limitations with high-glass-content materials because of its sensitivity to air gaps.
In other words, the acoustic imaging
technique does not generate false positives indicating damage where there is none.
Initially seen as an exotic discipline only used in high-end electronic systems and understood by highly skilled scientists, DSP methodologies have been broadly applied to consumer electronics, communications, automotive, instrumentation, medical electronics, tomography and acoustic imaging
, cartography, seismology, speech recognition, robotics etc.
TV systems and acoustic imaging
capabilities are "getting better," says Salmon.
The underwater acoustic imaging
technology utilized here was originally developed for the detection and disarming of undersea explosive mines," said Wallace Smith, ONR program manager.
An experimental approach called acoustic imaging
allows researchers at France's National Office for Aerospace Study and Research to "see" the unwanted noise generated by an airplane.
Professor Powers's research interests are in naval applications of optical devices, fiber optics, acousto-optic signal processing techniques, scalar wave diffraction and acoustic imaging
Tenders are invited for Geophysical logging by bore hole camera/ acoustic imaging

The purpose of acoustic imaging
is typically to locate, image and analyze internal defects.
