声光偏折效应球壳型换能器聚焦焦点峰值声压的测量
Measurement of peak pressure on the focusing acoustic field of spherical shell transducers based on acoustic optic deflection
摘要
Abstract
A simple experimental method for measuring the peak pressure on the focusing acoustic field of spherical shell transducers was designed by using the acousto-optic deflection effect .Based on the theoretical model of peak pressure and the maximum light deflection ,the peak pressure on the focusing sound field of the spherical shell transducer could be calculated by measuring the maximum light deflection . The COMSOL Multiphysics was used to simulate the radiated sound field of the focusing transducer .The results show that the relative error of the two methods is 7 .33% , which means that the theoretical calculation is in good agreement with the results obtained by COMSOL Multiphysics simulation .The experimental method has a wide application prospect in medical ultrasound rapid calibration .关键词
