摘　　要：在杨-顾算法的基础上,提出了一种基于二次成像的光学图像相位恢复算法.根据简化的光学成像系统模型得到了相机二次成像图像之间关系,即两者之间近似满足图像的薛定谔变换关系.利用图像的薛定谔变换和杨-顾算法实现了光学图像的相位恢复.实验结果表明:该算法能较好地重建光学图像,所恢复的相位信息中含有光学图像的一些基本信息.On the basis of Yang-Gu algorithm,we proposed a new algorithm of phase retrieval of optical image based on two imaging.We obtained the relationship of two imaging images according to the simplified optical imaging model,that is,the two images satisfy relationship of Schr dinger Transform.Based on this,we retrieved phase by using Schr dinger Transform of image and Yang-Gu algorithm.The experimental results showed that we could reconstruct the optical image while the retrieved phase information contained some basic information of optical image.
