ABSTRACT:
Sound signals are detected. Light signals are generated that pass through a membrane of a bubble within a trench. The sound signals cause deformations within the membrane of the bubble. The light signals are detected after the light signals have passed through the membrane. The sound signals are reconstructed from the light signals detected by the optical detector.
