本文报道了层状板状样品的光热效应（鼓效应）。如果板是薄的，则在夹紧的板上照射斩波激光会从热弹性弯曲产生弯曲振动。基于热波传播引起的温度矩，从理论上分析了层合板的热弹性弯曲特性。结果表明，由振动的幅值和相位信号可以得到板状样品的分层结构。因此，这种效应将是有用的光热检测技术的层状板。与传统的光热信号的比较也提出了一个分层的样品。
In this paper, we report a photothermal effect (drum effect) of the layered platelike sample. Irradiation of chopped laser light on the clamped plate produces flexural vibration from the thermoelastic bending if the plate is thin. The characteristics of thermoelastic bending of the layered plate are theoretically examined on the basis of the temperature moment caused by thermal wave propagation. It is shown that the layered structure of the platelike sample can be obtained from the amplitude and phase signals of the vibration. Hence this effect will be useful as a photothermal inspection technique for the layered plate. A comparison with the conventional photothermal signal is also presented for a layered sample.
