Tiny ultrasound detector achieves super-resolution imaging

07 Oct 2020
Tiny ultrasound detector
Sound idea: this silicon chip (3×6 mm) has multiple SWED detectors. The fine black engravings on the surface of the chip are the photonics circuits interconnecting the detectors, which are not visible. In the background is a larger scale photonics circuit on a silicon wafer. (Courtesy: Helmholtz Zentrum Muenchen / Roman Shnaiderman)
A device described as the world’s smallest ultrasound detector has been created by Vasilis Ntziach
