Abstract

Reflective intensity modulation fiber-optic acoustic sensor has a lot of advantages

such simple structure

high sensitivity as resisting to intense electromagnetic interference.A laser diode of a wavelength of 1310nm is used as its light source.The vibrated characteristic of diaphragm is studied based on vibrated theory when diaphragm is clamped at the edge.The diaphragm configuration is simplified and analyzed based on finite element analysis.The relationship of vibrated characteristic and geometric parameter is analyzed.Design methods and parameter selections are gained.A simple construction head of fiber-optic acoustic sensor is designed.Frequeucy respones of fiber-optic acoustic sensor is 350Hz

.5kHz;Sensitivity is 416.7mV/Pa.
