说明: 采用Laser - PVDF 实验系统对纳米AlP/ SiO2 中激光超声信号进行采集. 利用小波的多尺度分解、重
构和消噪功能,提取出直达波及其反射回波,测量了时间间隔和纳米AlP/ SiO2 的纵波声速. 结果证明小波变换
的方法能有效地处理复杂激光超声信号.(Using Laser- PVDF experimental system of nano-AlP/SiO2 Laser ultrasonic signal acquisition. Using wavelet multiscale decomposition, reconstruction and de-noising function, extracted from direct wave and its reflection echo measured time interval and nano-AlP/SiO2 of the longitudinal wave speed of sound. wavelet transform results show that the method can effectively deal with the complexity of laser ultrasonic signals.)
