Acoustical phase conjugation
Abstract
A mathematical and physical system able to reproduce, mechanically, a time reversed wave front is proposed. A multimicrophone array system records the sound wave. Then it reverses, by coherent time reversal, the signal. This technique may have radical consequences in geology, sea studies, and archeological investigation.
