We show experimentally that the recently proposed iterative shadowgraphic method can be applied to in-line digital holography, provided a suitable regularization step is introduced. We show that the method correctly solves the "twin-image" problem using just two samples of the intensity field scattered by a phase object. Field retrieval accuracy is significantly improved when compared to a reconstruction obtained with the defocusing variation algorithms.
我们通过实验表明，只要引入适当的正则化步骤，最近提出的迭代阴影照相法就可以应用于在线数字全息术。我们表明，该方法仅使用相位物体散射的强度场的两个样本即可正确解决“孪生像”问题。与使用离焦变化算法获得的重建相比，场恢复精度得到了显著提高。
