论文摘要
介电张量断层扫描重建显微对象的三维介电张量，并提供有关晶体结构取向和主要折射率的信息。由于介电张量断层扫描是基于传输测量值，因此它遭受了缺失的锥体问题，这会导致轴向分辨率差，低估折射率和光环伪影。在这项研究中，我们介绍了将总变异正则化对三维张量分布的概括。特别是，当应用于介电张量层析成像时，伪影的减少。
Dielectric tensor tomography reconstructs the three-dimensional dielectric tensors of microscopic objects and provides information about the crystalline structure orientations and principal refractive indices. Because dielectric tensor tomography is based on transmission measurement, it suffers from the missing cone problem, which causes poor axial resolution, underestimation of the refractive index, and halo artifacts. In this study, we present the generalization of total variation regularization to three-dimensional tensor distributions. In particular, demonstrate the reduction of artifacts when applied to dielectric tensor tomography.
