A technique for evaluating the acoustic properties of a layered medium utilizing an acoustic resonant phenomenon has been developed. The polymer film to be tested was attached onto the transparent glass plate and the acoustic resonant phenomenon via the film was observed together with acquiring the optical microscope image at the corresponding area. The acoustic-optical hybrid microscopy technique realized to visualize the fluctuation of the coating thickness on a steel plate and to detect the thermal degradation of a film. For example, the changes in the linear low-density polyethylene films were different depending on the methods and conditions for heat treatments and the difference could be detected by the present technique.

已经开发了一种利用声学共振现象来评估层状介质的声学特性的技术。将被测聚合物薄膜附着在透明玻璃板上，通过薄膜观察声学共振现象，同时获取相应区域的光学显微镜图像。声光混合显微技术实现了对钢板涂层厚度波动的可视化和对薄膜热降解的检测。例如，根据热处理方法和条件的不同，线性低密度聚乙烯薄膜的变化是不同的，并且这种差异可以通过本技术来检测。
