提出了一种测量低吸收固体绝对热光力学性质的时间分辨热镜方法。导出了表面位移的热弹性方程和探测器平面上探测光强度的解析表达式。在光学玻璃中进行了实验证明，拟合的参数与以前的文献数据的热，光学和机械性能吻合良好，这表明该方法是一个有用的工具，用于表征各种透明材料。
A time-resolved thermal mirror method for measurements of absolute thermo-optical-mechanical properties of low absorbing solids is presented. The thermoelastic equation for the surface displacement and an analytical expression for the probe beam intensity at the detector plane were derived. Experimental proofs were performed in an optical glass and the fitted parameters are in good agreement with previous literature data for thermal, optical, and mechanical properties, suggesting that the method is a useful tool for the characterization of a wide range of transparent materials.
