中文摘要:
      介绍了声透镜波束形成的基本原理和分析方法,分析了柱面型声透镜的设计方法。用ZEMAX光学软件设计并用ABS塑料制作了一个组合声透镜,在水池中完成其多个参数的测量。在频率500kHz和20°的视场范围内该声透镜的角度分辨率为1°。实验结果表明,该声透镜系统的波束宽度、旁瓣高度和视场范围均达到了设计要求,并很好的验证了柱面型声透镜的聚焦性能。
英文摘要:
      This paper introduces an analyzing method and principle of beamforming with acoustic lenses,and analyses a design method of cylindrical acoustic lenses.An acoustic lens system is designed by ZEMAX and made by ABS,and tests of several parameters have been completed in a cistern.The lens system achieves an angular resolution of 1deg.at 500 kHz with a 20deg.field of vision.Experimental result shows that the lens system satisfies the demand of design in beam width,sidelobe levels and field of vision,and it well verifies the focusing properties of cylindrical acoustic lenses.
