摘要
文章报导了为生物医学研究用的聚焦换能器 ,可以在水中发出延续时间为一个半周期 ,主频为 10MHz的超声脉冲。文中介绍了研制工艺 ,并给出换能器以下的物理特性 :1.用光学法拍摄的换能器在水中的聚焦过程 ;2 .激发换能器的电脉冲波形及接收电压的波形和幅值 ;3 .
An ultrasonic focused transducer mainly used in biomedical technology, with its main frequency of 10MHz and the duration of one and a half periods, is described in detail in this paper. The following physical properties of this transducer are given: 1.The focused acoustic field recorded by an optical method; 2.The electric waveform for triggering the transducer and the related waveform received by another transducer; 3.The testing results of a sample.
