3-D acoustical imaging using micromechanical hydrophones. K.M. Houston. Sea Technol., September 1996, 37(9), 29--34.
The development is reported of micromechanical acoustic sensors including an audio-frequency micromechanical hydrophone (MMH), a condenser microphone, and a high-frequency MMH. The various design approaches for these acoustic lens, beam formed configurations, systems less susceptible to scattering than light, suitable for littoral, turbid waters, for use by divers and ROV operators are outlined. 5 refs.
