简要介绍了全光纤加速度地震检波器的工作原理和敏感元件的结构特征 ,详细描述了质量块横向振动限制膜片的设计理论。实验结果表明 :采用双膜片限制质量块横向振动的检波器的频谱较未加限制膜片的频谱有明显改善 The work principle of the all-fiber acceleration geophone and the structural characteristics of the sensor are briefly introduced. The design theory of the transverse vibration limiting diaphragm of the mass is described in detail. The experimental results show that the frequency spectrum of the detector with double diaphragm to limit the lateral vibration of the mass is better than the spectrum without the diaphragm
