LiNbO 3 的性质的调查经由导致加速的效果的光测弹性的波导被介绍。一张新奇三部件的混血儿综合的光加速表基于有 LiNbO 3 的 Mach-Zehnder 干涉仪，光测弹性的波导被设计了，它能够在高精确性的地震探索检测地震加速。Mach-Zehnder 干涉仪成功地被制作，灯光的测试过去常检查它的质量。加速表的频率反应特征被测量。有 3549 Hz 的反响的频率的加速表被表明显示出在 100 ∼3000 Hz 的范围回答特征的好线性频率。加速表也显示出好稳定性和一致性。试验性的结果显示在轴上的产量并且跨轴分别地是 147 和 21.3 mV。

An investigation of the properties ofa LiNbO3 photoelastic waveguide via the acceleration-induced effect is presented. A novel three-component hybrid-integrated optical accelerometer based on a Mach-Zehnder interferometer with a LiNbO3 photoelastic waveguide has been designed, which is capable of detecting seismic acceleration in high-accuracy seismic exploration. The Mach-Zehnder interferometer was successfully fabricated and a lighting test used to check its quality. The frequency response characteristic of the accelerometer was measured2 The accelerometer with a resonant frequency of 3549 Hz was demonstrated to show good linear frequency responding characteristics in the range of 100-3000 Hz. The accelerometer also shows good stability and consistency. Experimental results indicate that the outputs of the on- and cross-axis are 147 and 21.3 mV, respectively.
