Swept Frequency Acoustic Interferometry and its Applications
JRO 1&2- JR Oppenheimer Center, Los Alamos, New Mexico, United States, 87545Swept Frequency Acoustic Interferometry (SFAI) was developed specifically to identify highly toxic chemicals inside sealed munitions almost two decades ago. SFAI is based on setting up standing waves (resonance) inside a fluid-filled (liquid, mixture, suspension, emulsions, gas etc.,) container. These resonances are typically observed over a wide range of ultrasonic frequency in the form of ...
