In an earlier study, the authors presented a calibration technique for a triaxial bipolar electrode array (EA) that used 72 data points collected during a global sweep of the electric field vector relative to the EA axes. Although necessary for the initial characterization of the EAs, this data requirement has to be significantly reduced for the technique to become a practical tool. Therefore, in the present study, an analysis is performed to determine the relation between the number of data points used in the calibration and the mean root-mean-square error. The analysis shows that 18 data points can produce results nearly identical to those obtained with the 72-point calibration, thus reducing the required amount of data fourfold.
在早期的一项研究中,作者提出了一种用于三轴双极电极阵列(EA)的校准技术,该校准技术使用了在电场矢量相对于EA轴的全局扫描期间收集的72个数据点。尽管这些数据对于EA的初始表征是必要的,但为了使该技术成为一种实用工具,必须大幅减少这一数据要求。因此,在本研究中,进行了一项分析以确定校准中使用的数据点数量与均方根误差均值之间的关系。分析表明,18个数据点产生的结果与使用72点校准获得的结果几乎相同,从而将所需的数据量减少了四倍。
