Abstract

Based on the theoretical model and simulation, this paper presents the acoustic detective sensitivity of three types of optical fiber acoustic sensors – RIM-FODS (reflective intensity modulated fiber optic displacement sensor), extrinsic F-P (Fabry-Perot) interferometer and all-fiber photoelastic interference sensor. Three designed optical fiber acoustic sensor systems are implemented to analyze the performance of each type and tested to investigate the detective sensitivity at 1kHz 94dB SPL (sound pressure level). The experimental results are in good agreement with those obtained by theoretical analysis and simulation.
