Description: This image shows the acoustic hyperlens, which is fashioned from 36 brass fins arranged in the shape of a hand-held fan. Each fin is approximately 20 sm long and three mm thick. Ultrasound and underwater sonar devices could "see" a big improvement thanks to development of the world's first acoustic hyperlens. Created by Berkeley Lab researchers, the acoustic hyperlens provides an eightfold boost in the magnification power of sound-based imaging technologies. Clever physical manipulation of the imaging sound waves enables the hyperlens to resolve details smaller than one sixth the length of the waves themselves, bringing into view much smaller objects and features than can be detected using today’s technologies.
