摘要
为了探明声波在复杂介质内部的传播规律,综合应用声学、嵌入式、机械、电子和计算机接口等技术研制了实时声波二维成像系统。该系统能将声波在固体内部传播的过程可视化,用所研制的实时声波二维成像系统绘制出超声波在有机玻璃板中传播的实时波形图,能为构建声波在复杂介质中传播的工程应用的可视化模型提供基础条件。
In order to find out the propagation of the ultrasonic wave in complex media accurately, the technology of acoustics, embedded, machinery, electronics and computer interface have been integrated and used to develop a real time 2-D acoustics imaging system. The propagation of ultrasonic wave in solid can be visible, and the real time acoustics waveforms propagating in the Plexiglas plate mapped by the 2-D imaging system are presented. The 2-D imaging system can provide the basic conditions to build the engineering model of acoustic wave propagation in complex media.
