球面曲面换能器是一种常见的超声波传感器,广泛应用于医学、工业和科学研究等领域。球面曲面换能器的性能参数对于超声波成像和检测的准确性和可靠性至关重要。因此,测量球面曲面换能器的电声参数和声输出功率是非常必要的。

IEC TS 62903:2018提供了一种基于自互易法的测量球面曲面换能器电声参数和声输出功率的标准方法。该方法利用了球面曲面换能器的自互易性质,通过测量球面曲面换能器在发射和接收模式下的电压响应,计算出球面曲面换能器的电声参数和声输出功率。

该标准详细描述了测量球面曲面换能器电声参数和声输出功率的实验步骤和计算方法。其中,实验步骤包括球面曲面换能器的准备、测量系统的搭建、测量球面曲面换能器在发射和接收模式下的电压响应等。计算方法包括计算球面曲面换能器的灵敏度、声输出功率、声压级等参数。

IEC TS 62903:2018的实施可以提高球面曲面换能器的测量精度和可靠性,为超声波成像和检测提供更加准确和可靠的数据支持。
