ACOUSTOGRAPHY is an ultrasound imaging method where a novel, super high-resolution 2D ultrasound detector (AO sensor) is used to produce instant x-ray-like ultrasound images. A direct comparison between ACOUSTOGRAPHY and C-scan is shown below on an Aerospace Composite Standard Panel. Note the higher resolution provided by ACOUSTOGRAPHY; defects are square 3/8”, 5/16”, 1/4”, 3/16”, and 1/8” and both images were taken at 5MHz ultrasound frequency.
The basic components needed to perform Acoustography NDE are: 1) AO-Sensor (Imaging Screen); 2) Wand Transducer (ultrasound emitter); 3) Optical imager Detector. The Wand Transducer is swept across the part held over the AO sensor to form instant x-ray like ultrasound images of the part revealing anomalies in the test part. The image formed on the AO sensor is viewed and digitally recorded using the Optical Imager.
We offer ACOUSTOGRAPHY NDE as a standalone system, or as an add-on ACOUSTOGRAPHY NDE capability to existing C-scan systems.
Our small Table-Top system is perfect for the NDE researcher, providing a simple, practical tool for quick evaluation of composite parts and for providing near real-time monitoring of damage growth in coupons subject to load.
Our retrofit system package is perfect for providing add-on Acoustography NDE capability to customers with existing C-scan systems.
Our fully-automated systems are perfect for the manufacturing floor, capable of enhancing inspection throughput by up to 10 times.
ACOUSTOGRAPHY components can also be purchased, along with data electronics and software package, by customers desiring to build their own systems or wanting to retrofit components to have add-on ACOUSTOGRAPHY NDE capability to their C-scan systems.
