摘要翻译：
针对具有锚点的强连接的一般PTYCHORGICH测量方案，分析了具有未知掩模和目标的PTYCHORGICH。在对掩码相位有一定限制的情况下，证明了掩码目标估计必须是块相位因子与真实掩码目标的乘积。这种局部唯一性表现在相位漂移方程中，该方程决定了由ptychographic移位连接的不同位置的模糊度。所提出的混合方案有效地将整个域的模糊度连接起来，从而产生明显的模糊度轮廓，从而具有全局唯一性，即块相位具有仿射轮廓，目标和掩模可以同时恢复到恒定的缩放因子和仿射相位因子。

英文摘要：
  Ptychography with an unknown mask and object is analyzed for general ptychographic measurement schemes that are strongly connected and possess an anchor.   Under a mild constraint on the mask phase, it is proved that the masked object estimate must be the product of a block phase factor and the true masked object. This local uniqueness manifests itself in the phase drift equation that determines the ambiguity at different locations connected by ptychographic shifts.   The proposed mixing schemes effectively connects the ambiguity throughout the whole domain such that a distinct ambiguity profile arises and consequently possess the global uniqueness that the block phases have an affine profile and that the object and mask can be simultaneously recovered up to a constant scaling factor and an affine phase factor.
