本文考虑用窗函数进行二维相位恢复。首先，我们从三个信号的傅里叶强度来解决二维信号的唯一性和重建：原始信号，窗口w（m,n）的信号窗口和它的互补窗口w/下标c/(m,n)=1-w（m,n）的信号窗口。然后考虑无补充窗的相位恢复。我们提出了一个条件，在这个条件下，信号可以由原始信号和加窗信号的傅里叶强度唯一地指定为w（m,n）。我们还提出了一种重建算法。
This paper considers two-dimensional phase retrieval using a window function. First, we address the uniqueness and reconstruction of a two-dimensional signal from the Fourier intensities of the three signals: the original signal, the signal windowed by a window w(m,n) and the signal windowed by its complementary window w/sub c/(m,n)=1-w(m,n). Then we consider the phase retrieval without a complementary window. We develop conditions under which a signal can be uniquely specified from the Fourier intensities of the original signal and the windowed signal by w(m,n). We also present a reconstruction algorithm.
