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.

无分析仪线性二向色印刷术

线性二色性是表征透射矩阵和确定材料中的晶体或轨道取向的重要工具。为了获得此类材料传输特性的高分辨率映射，我们在 ptychographic 成像中引入了线性二色性散射模型，然后开发了一种高效的两阶段重建算法。使用所提出的算法，可以通过使用最少三个不同偏振角的 ptychography 测量来恢复没有分析器的二向色传输矩阵，并借助空白区域来消除相位模糊。
