説明
<jats:p>An acoustic sensor using evanescent optical coupling between multimode optical fibers has been successfully demonstrated to have a detector shot-noise limited sensitivity at a sound pressure level of about 50 dB re 1 μPa/(Hz)12. The bandwidth of the sensor is dc to 8000 Hz. Construction of the device is described, along with a theoretical description of its operation compared to observed performance.</jats:p>
