摘要
本文将谐波技术应用于激光扫描声学显微镜(SLAM)换能器,提出了提高其工作频率的方法。实验实现了SLAM从100MHz提高到300MHz。并就一些样品进行了测试,得到了较满意的声象。
The harmonic technigue is used to increase the operating frequency of the transducer of the SLAM.The increase of the operating frequency from 100 MHz to 300 MHz is realized through experiments.Some samples are successfully imaged on TV Screen.
