Active Nonlinear Acoustic Sensing of an Object with Sum or Difference Frequency Fields

Active Nonlinear Acoustic Sensing of an Object with Sum or Difference Frequency Fields

A number of nonlinear acoustic sensing methods exist or are being developed for diverse areas ranging from oceanic sensing of ecosystems, gas bubbles, and submerged objects to medical sensing of the human body. Our approach is to use primary frequency incident waves to generate second order nonlinea...
