Sculpting sound fields with acoustic holograms

Abstract

Using optical holograms, we can modulate light wavefronts to generate visible images. Can we do the same with sound waves? Acoustic holograms can render sonic images, shaping the areas where mechanical waves present a high amplitude, and areas where the media is at rest. In this plenary talk, we will present an overview of the use of acoustic holograms, and how they can be applied in biomedical ultrasound applications, in particular in emerging therapeutic applications of focused ultrasound, but also in other fields like audible engineering acoustics or contactless particle trapping, to tailor sound waves in unprecedented ways.
