| 摘 要： | 时间反转（TR）技术可实现目标回波的聚焦，提高检测分辨率。针对Lamb波无损检测的需要，开发了用于TR测量的测试系统。针对AFG3000系列波形发生器。编写了基于LABVIEW的控制程序，该程序通过代码转换的方法，将波形参数转换成波形发生器能够识别的BNF代码，从而向波形发生器发出指令。在检测过程中即时将检测波形时间反转后再次发射，实现了检测与激励系统的集成。

| Abstract: | Time-reverse technology can be used to do reflect-wave focus,which can improve the resolving power of the testing. This literature has developed a novel testing system used to do the TR measurement according to the need of the lossless examination of the Lamb wave. The control program is also given based on LABVIEW,in consistent with the AFG3000 series wave generators. And the program has transformed the parameters of the wave into the BNF codes which can be recognized by the wave generator using the method... |
