Similar to Chapter 3, the fiber‐optic extrinsic Fabry–Perot interferometric () acoustic vibration sensor has a similar structure with the pressure sensor because acoustic pressure is also a small pressure. So in the sensor structure, the most important is the diaphragm material selection and structure design, which is the main topic of this section.
Sound wave is a kind of micro‐pressure signal with fast frequency, which is reflected in the rapid vibration of medium. The characteristics of sound are determined by the frequency and mode ...
