我们首先讨论离散分数傅立叶变换，并给出一些基本性质。然后，我们提出了一种递归算法来实现相位恢复从分数傅里叶变换域中的两个强度。与传统的迭代算法相比，这种方法可以大大简化计算操作，并且不需要初始相位估计。仿真结果表明，该方法可以成功地恢复相位从两个强度。
We first discuss the discrete fractional Fourier transform and present some essential properties. We then propose a recursive algorithm to implement phase retrieval from two intensities in the fractional Fourier transform domain. This approach can significantly simplify computational manipulations and does not need an initial phase estimate compared with conventional iterative algorithms. Simulation results show that this approach can successfully recover the phase from two intensities.
