We demonstrate the nonlinear recovery of diffused images in a self-focusing photorefractive medium. The method is based on the convolution property of nonlinearity, in which related modes reinforce each other as they propagate. The resulting mode coupling enables energy transfer from the scattered light to the underlying signal. The dynamics is well described by a model in which the signal seeds a modulation instability in the diffused background.
我们展示了自聚焦光折变介质中漫散射图像的非线性恢复。该方法基于非线性的卷积特性，在该特性中，相关模式在传播过程中相互增强。由此产生的模式耦合使得能量从散射光转移到潜在的信号上。该动力学可以很好地用一个模型来描述，其中信号在漫散射背景中引发调制不稳定性。
