平凹线聚焦透镜焦线长度的控制方法
The length control of focal line in the plano-concave line focusing acoustic lens
摘要
Abstract
The way to control the length of focal line in the plano-concave line focusing acoustic lens is presented.The area of plano-concave cylindrical acoustic lens is changed into a new area formed from a circular arc of xOy plane rotating around the z-axis.Based on the Huygens′ principle,the sound model of the lens is established and the numerical simulation is finished.The conclusion shows that one could control the focal line length of the plano-concave line focusing acoustic lens by changing the radius of arc and the radius of rotation.This work could give some help in the design line focusing acoustic lens.关键词
