本文提供一种高斯超声换能器的设计.可以利用它产生任意束宽的高斯型声场.这种设计采用曲面背电极,而不是通常的平面电极.用激光干涉拾振技术对换能器表面的振动分布进行测量.测量结果与设计理论良好吻合.
This article provides a Gaussian ultrasonic transducer design that can be used to produce any beamwidth Gaussian sound field.This design uses the curved back electrode, rather than the usual planar electrode.Using laser interfering pick-up technology on the transducer surface Of the vibration distribution of the measurement results are in good agreement with the design theory.
