Generation of Intense Low-Frequency Collimated Sound Beams by Nonlinear Acoustics and Detection by a Millimeter-Wave Vibrometer

Abstract

In this work, we designed, developed and tested nonlinear ultrasonic arrays for the purpose of generating an intense, collimated beam of sound to be directed at targets such as buried landmines. In order to make a completely noncontacting system, with insonification via the nonlinear array, we also developed a sensitive millimeter wave vibrometer to detect the resulting ground motion.
