摘要：
The electrostriction coefficient can be accurately measured by using small length variation based on inverse piezoelectric effect. The conventional optical measuring method based on direct detection of light intensity distribution to obtain small length variation is restricted by light source power stability and environmental perturbation, and can not reach high measuring accuracy. This paper uses the combination of multi-beam laser heterodyne technique with sinusoidal modulation technique to load small length variation to the heterodyne signal frequency. By researching on the theoretical models of heterodyne signal for measuring small length variation, and the relationship between heterodyne signal frequency and electrostriction coefficient, the direct intensity detection can be replaced by heterodyne signal frequency detection, the effects of light source power stability and environmental perturbation can be removed. Many values of small length variation can be got by using the frequency demodulation simultaneously. Processing these values by weighted-average, can get length variation accurately, and eventually get value of electrostriction coefficient of piezoelectric material by the calculation. The measuring accuracy of electrostriction coefficient can be further improved. Based on this, the theoretical simulation research on electrostriction coefficient of testing sample can be acted, the obtained results show that the relative measurement error of this method is just 0.28%. The measuring accuracy is improved one order of magnitude compared with existing technique. © 2017, Science Press. All right reserved.
