Abstract

一种超声换能器、超声波扫描系统及加工方法,超声换能器(1),包括:第一电极(1011)、第二电极(1012)和压电材料(1013);第一电极(1011)、第二电极(1012)和压电材料(1013)形成至少一个超声换能模块(10),超声换能模块(10)包括至少两个超声换能单元(101);压电材料(1013)设置于第一电极(1011)和第二电极(1012)之间,第二电极(1012)用于输入或输出电信号;同一个超声换能模块(10)中,每两个超声换能单元(101)的压电材料(1013)的厚度不相同。由于不同超声换能单元(101)的压电材料(1013)厚度不同,能够接收不同频率的超声波,可以检测到不同深度的信息,使得超声波检测应用范围更广,适应性更强。
