单臂测量
Based theory of the fiber optic accelerometer is presented in details , according to the the principle of phase modulation a new experimental scheme is described . in this scheme , a center supported flexural disk design is chosen as the sensing mechanism , the fiber of the interferometer is attached on each side of the flexural disk , such design is helpful to the desirable features such as high acceleration sensitivity and immunity to extraneous measurands
第二章中从不同方面详细介绍了相位调制型光纤加速度计的基础理论，并由此提出了一种新型的加速度计测量方案，该方案通过在柔性盘的上下侧面粘上干涉仪双臂光纤形成推挽式系统，可以有效地消除光纤干涉仪易受温度等环境影响的缺点，并由于采用推挽方案，使灵敏度比采用单臂测量提高了一倍。
