We extend the Gerchberg-Saxton algorithm to phase retrieval in a nonlinear system. Using a tunable photorefractive crystal, we experimentally demonstrate the noninterferometric technique by reconstructing an unknown phase object from optical intensity measurements taken at different nonlinear strengths.
我们将格奇伯格 - 萨克斯顿算法扩展到非线性系统中的相位恢复。利用一个可调谐光折变晶体，我们通过在不同非线性强度下进行光学强度测量来重建一个未知相位物体，从而通过实验证明了这种非干涉技术。
