In a collaboration between the Sydney Harbour Port Authority and Acoustic Imaging, Geoscience Australia's SBAS positioning trial was used to dock the 348-metre Quantum class cruise ship at Circular Quay on her most recent berthing. The SBAS trial, funded with $12 million from the Australian ...
The lead scientist of Acoustic Imaging's maritime programs, Nicole Bergersen said the docking of Ovation of the Seas, which is over 330 metres long and too tall to sail beneath the Sydney Harbour Bridge, was a unique opportunity to test how the use of SBAS technology could potentially benefit the ports of ...

New Metamaterial Manipulates Sound to Improve Acoustic Imaging. Dec. 16, 2015 — Researchers have developed a metamaterial made of paper and aluminum that can manipulate acoustic waves to more than double the resolution of acoustic imaging, focus acoustic waves, and control the ... read more ...
Using acoustic imaging, Berge detected zooplankton as deep as 80 meters fleeing laterally when they sensed light. He also caught them scattering up to 500 meters away in the surface layers of the sea. This means plankton tows and water samples taken from research ships in the Arctic night may have ...
The uncertainty that lies below the surface of the sea provides a number of industries with incredible challenges when conducting their daily business. From offshore structure installation and inspection, to the defense of our ports, and construction of national power generation assets, all subsea industries ...

Figure 1: Using acoustic imaging to visualize sound from a wind turbine. Arrays of microphones are used to synthesize the recorded noise and localize regions of high amplitude acoustic vibrations at source location (source: http://www.filopopers.nl/windturbine-geluid/). These acoustic cameras (known as ...
Understanding the mechanics of megathrusts can help scientists more accurately estimate the risks facing local populations. Scientists used advanced acoustic imaging technology to survey the corrugated ridges, or grooves, along the interface of the two plates. The patterns are similar to ridges found at the ...

“By combining opto-acoustic imaging and traditional ultrasonic imaging in such a novel manner, the system can employ just one ultrasonic transducer to detect all three ultrasound pulses and use the same set of analog and digital electronics to acquire and process both types of signals,” he said.
Edwards worked with a team of geophysicists at UC Santa Cruz, the U.S. Geological Survey, the University of Texas-Austin, and McGill University to obtain 3-dimensional imagery of the fault interface using cutting-edge acoustic imaging technology. The long grooves, or corrugations, they observed along ...
Acoustic Imaging of Oceanic Mixing in the Gulf of Mexico. Detailed analysis of acoustic reflections suggests that vertical mixing of oceanic water is enhanced at greater depths, thanks to weak stratification and the roughness of the seabed. Source: Journal of Geophysical Research: Oceans. Aerial shot of ...
The discovery of the USS Lexington comes less than one year after the discovery of the USS Indianapolis. EdgeTech takes great pride in knowing it's high quality, reliable underwater acoustic imaging systems continue to assist in these historical endeavors. • United States • Australia • sonar technology ...

The MM-Wave Group also carry out research in Acoustic Interferometry and Imaging techniques. At first appearance, acoustics seems an odd companion to mm-waves, but the two areas have a lot in common. In each case we are dealing with wide-bandwidth signals with wavelengths of the order of millimetres to centimetres. The group uses an anechoic chamber in our Physics building. The main project so far has been to develop a novel way to measure the imaging performance of hi-fi loudspeakers....
