HTTP:: Acoustic Hyperlens Improves Sound Based Imaging Technologies
--------
Scientists at the US Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) have recently managed to create an innovative, new device that may have the ability to boost the power of ultrasound medical devices and submarine radars by more than 800 percent. The new acoustic hyperlens is constructed in such a manner that it can detect objects that are one sixth of the size of the sound waves themselves, PhysOrg reports. This means that the device could be used to resolve objects that are significantly smaller than anything current technologies can discover. Mounted on submarines, for example, it could make for an advanced imaging method that could help captains recognize obstacles or enemy vessels faster and more accurately. With as much information as possible at their disposal, the submarines could then make the correct decision, and not have to guess the nature of the threat anymore. In case of medical devices, being able to resolve smaller deta!
ils could lead to doctors discovering development anomalies in babies faster, which could, in turn, increase their chances of a normal life. “We have successfully carried out an experimental demonstration of an acoustic hyperlens that magnifies sub-wavelength objects by gradually converting evanescent waves into pr...
