介绍了对脉冲受激热散射光学技术的改进，使其能够实时采集数据。该方法用于表征附着在硅衬底上的聚酰亚胺薄膜的伪瑞利声模式，并证明了其作为提取薄膜涂层弹性常数的手段的潜在用途。
A modification of the optical technique of impulsive stimulated thermal scattering that allows real-time data acquisition is introduced. The method is used to characterize the pseudo-Rayleigh acoustic modes of thin (approximately 1 mum) polyimide films attached to silicon substrates and its potential use as a means for extracting the elastic constants of thin-film coatings is demonstrated.
