摘要 在对高强度聚焦超声(HIFU)场中温度和产压性质分析的基础上,提出了根据光纤的光弹效应,用偏振光进行声压的测量,并从理论上进行了分析,得出了一些有用的公式。 According to the analysis of temperature and acoustical press in HIFU fields, the acoustical press was detected using polarized light basing on elasto-optic effect.The theoretical mechanism was deduced, and some valuable conclusion and formulas were obtained.
