摘要
A novel configuration of a single-loop Sagnac interferometric acoustic sensor based on Asymmetric desensitization of a half of the coil (loop) to phase modulation is presented. Sensitivity as high as 10(-5) Pa at a maximum frequency response of similar to 8 kHz is demonstrated in underwater experiments.
