The elasto-optic properties of liquids on the basis of the first principles of acousto-optics were theoretically investigated. A relationship for calculating the elasto-optic constant of liquids using only the refractive index was obtained. The refractive index values corresponding to the maximum elasto-optic constant for polar and nonpolar liquids were determined. Calculations for about 100 liquids were performed and compared with known experimental data. This study significantly extends our understanding of the acousto-optic effect and has practical applications for predicting the elasto-optic constant of a liquid and estimating its wavelength dispersion.
基于声光的第一性原理，对液体的弹光特性进行了理论研究。得到了仅使用折射率来计算液体弹光常数的关系式。确定了极性和非极性液体对应最大弹光常数的折射率值。对约100种液体进行了计算，并与已知实验数据进行了比较。这项研究显著扩展了我们对声光效应的理解，在预测液体的弹光常数及其波长色散估计方面具有实际应用价值。
