The (http://patft1.uspto.gov/netacgi/nph-Parser?patentnumber=10275633) second patent is the "Acoustic imaging
system for spatial demodulation of acoustic waves." The technology works similarly with the first patent but is differentiated via its transducer placement.
During acoustic imaging
, the spaces between the cracks helped to reflect ultrasound and create the anomaly seen in Figure 1.

The fundamental theory of acoustic imaging
is that the acoustic speed in a medium is a function of the medium temperature.
There are few papers working on acoustic imaging
in air for the detection of human beings.
The topics include the mechanics of elastic waves and ultrasonic nondestructive evaluation, guided waves for plate and pipe inspection, characterizing materials with nonlinear ultrasonic techniques, the theory and applications of scanning acoustic microscopy and scanning near-field acoustic imaging
, and fiber-optic sensors for monitoring structural health.
The accomplishment provides faster turnaround times of both elastic and acoustic imaging
of microseismic events for customers.

Researchers operated two WHOI-built REMUS autonomous underwater vehicles, owned by the Waitt Institute, with advanced acoustic imaging
and electronic still cameras.
The team will be using cutting-edge robots, acoustic imaging
, sonar technologies and high resolution optical, video and 3D imaging.
The company has been chosen to offer an acoustic imaging
system for its new range of Autonomous Inspection Vehicles (AIVs).
In performing acoustic imaging
of an MLCC, the scanning ultrasonic transducer of the acoustic microscope pulses ultrasound into the MLCC several thousand times a second as it moves back and forth across the MLCC.
