In a previous paper [Opt. Commun.225, 19-30 (2003)] we presented a method to reconstruct two-dimensional complex amplitudes by using the ambiguity function of one-dimensional intensity scans, obtained from two optical setups involving cylindrical lenses. We demonstrate that the internal redundancy of the ambiguity function can be utilized to improve the efficiency of this method even further. We show that the phase reconstruction errors can be minimized with an appropriate algorithm, and we present experimental data that illustrate the efficient reconstruction of a two-dimensional phase element.
在之前的一篇论文[《光学通信》225, 19 - 30 (2003)]中，我们提出了一种通过使用一维强度扫描的模糊函数来重建二维复振幅的方法，该一维强度扫描是从涉及柱面透镜的两个光学装置中获得的。我们证明了模糊函数的内部冗余可用于进一步提高该方法的效率。我们表明，通过适当的算法可以将相位重建误差最小化，并且我们展示了说明二维相位元件高效重建的实验数据。
