凝视水晶球：球上电子背散射衍射图分析和互相关
Gazing at crystal balls: Electron backscatter diffraction pattern analysis and cross correlation on the sphere
摘要：
本文提出了两种新的电子背散射衍射（EBSD）图的球面分析算法：（1）用球面Radon变换进行带定位和带轮廓分析;（2）用球面互相关确定方向。这些新的方法被正式介绍，并确定其精度使用动态模拟模式。我们证明了他们的效用与实验数据集从铁素体铁。我们的研究结果表明，EBSD模式的分析提供了一个优雅的方法，揭示这些丰富的晶体学数据来源的信息。
英文摘要：
We present spherical analysis of electron backscatter diffraction (EBSD) patterns with two new algorithms: (1) band localisation and band profile analysis using the spherical Radon transform; (2) orientation determination using spherical cross correlation. These new approaches are formally introduced and their accuracies are determined using dynamically simulated patterns. We demonstrate their utility with an experimental dataset obtained from ferritic iron. Our results indicate that the analysis of EBSD patterns on the surface of the sphere provides an elegant method of revealing information from these rich sources of crystallographic data.
