本文讨论了用声表面波(SAW)位移传感器进行微小位移测量的两种方法:一种是用两个石英基片来组成 SAW 延迟线振荡器进行位移测量;另一种是利用一个石英基片来组成 SAW 谐振器(SAWR)或延迟线振荡器来实现位移测量。这两种方法对于精密工业的位移测量及其可以转化为位移测量的其它物理参量的测量都是十分有用的。本文还介绍了两大类型的 SAW 加速度计:一种是以伸张应力效力为基础的 SAW加速度计,它的敏感元件发生的是伸张或压缩变形;另一种是以弯曲应力效应为基础的SAW加速度计,它的敏感元件发生的是弯曲变形。另外,本文还对 SAW 加速度计的性能进行了分析、讨论。

The frequency characteristic of surface acoustic wave resonator(SAWR) and its oscillator(SAWO) are under the influence of their surrounding temperature and temperature-shift.After this physical phenomenon was analyzed,a new SAW accelerometer with 4-SAWR based on floating zero principle is put forward theoretically.The elementary method to increase measure-accuracy and precision of the SAW accelerometer is for reducing temperature influence to set up a floating zero SAWR which has same temperature frequency characteristic as the measuring SAWR.Another advantage of the new structure of SAW accelerometer is reducing technological requirement to the SAWR.

分析了温度漂移对声表面波谐振器(SAWR)及其声表面波振荡器(SAWO)频率特性、以及对SAW加速度计测量准确性的影响,探讨了提高SAW加速度计测量准确度的方法,提出了一种基于浮动零点原理抑制温度共模干扰的双对SAWR加速度计设计方案。本方案不仅通过设置浮动零点SAWR抑制了SAWO频率-温度漂移对SAW加速度计测量准确度的干扰,还在一定程度上降低了对SAWR表面制造工艺的要求。
