论文摘要
当连贯的光通过随机散射介质传播并直接使用常规光学方法无效时，波前会加扰。在本文中，我们提出并演示了通过不透明散射层成像成像的结构化光照明。提出的技术是无参考的，并且能够从斑点模式的强度中恢复复杂场。这是通过在结构化的光照射中利用相位转移来实现的，并在强度相关测量中应用斑点模式的空间平均。提出了实验设计，并基于实验设计的模拟结果显示，通过散射层证明了不同复合物值对象的成像。
The wavefront is scrambled when coherent light propagates through a random scattering medium and which makes direct use of the conventional optical methods ineffective. In this paper, we propose and demonstrate a structured light illumination for imaging through an opaque scattering layer. Proposed technique is reference free and capable to recover the complex field from intensities of the speckle patterns. This is realized by making use of the phase-shifting in the structured light illumination and applying spatial averaging of the speckle pattern in the intensity correlation measurement. An experimental design is presented and simulated results based on the experimental design are shown to demonstrate imaging of different complex-valued objects through scattering layer.
