In this episode, we dive into the world of acousto-optics, where light is used to visualize and measure sound-- particularly acoustic phenomena that are difficult to observe. Samuel Verburg (Technical University of Denmark) and Kenji Ishikawa (NTT Communication) share the history of this field of research, as well as discuss modern day applications and potential uses for acousto-optic sensing in the future.
