论文摘要
线性 - 分解是表征透射基质并确定材料中的晶体或轨道取向的重要工具。为了获得此类材料的传输特性的高分辨率映射，我们在PtyChographic Imaging中介绍了线性 - 分数散射模型，然后开发有效的两阶段重建算法。使用所提出的算法，可以通过空旷的区域的帮助去除相位的歧义，可以通过使用少量三个不同的极化角度的Ptychography测量值来恢复无分析仪的二分性传输矩阵。
Linear-dichroism is an important tool to characterize the transmission matrix and determine the crystal or orbital orientation in a material. In order to gain high resolution mapping of the transmission properties of such materials, we introduce the linear-dichroism scattering model in ptychographic imaging, and then develop an efficient two-stage reconstruction algorithm. Using proposed algorithm, the dichroic transmission matrix without an analyzer can be recovered by using ptychography measurements with as few as three different polarization angles, with the help of an empty region to remove phase ambiguities.
