Piezoelectric-Modulated Sound Pressure Sensor Using a Fiber Bragg Grating

Piezoelectric-Modulated Sound Pressure Sensor Using a Fiber Bragg Grating

碩士 === 逢甲大學 === 電機工程所 === 98 === This thesis shows a sound level sensor based on a fiber Bragg grating (FBG) and a piezoelectric actuator. Deformation is generated by the applied voltage to piezoelectric actuator which is used to measure the sound pressure. An Optical Spectrum Analyzer (OSA) is used...
