摘要:

光学衍射层析成像是一种不可或缺的工具,研究对象的三维,由于其能够准确地重建散射对象。到目前为止,这种技术一直限于相干光,因为空间相位信息需要解决逆散射问题。我们介绍了一种方法,扩展光学衍射层析成像空间不相干的对比机制,如荧光发射。我们的策略模仿了两个空间相干照明光束的相干散射过程。干涉照明图案在荧光发射的时间变化中编码空间相位,从而允许非相干荧光发射模仿相干照明的行为。的时间变化允许恢复的传播相位,因此可以恢复与逆散射模型的非相干荧光发射的空间分布。

英文摘要:

Optical diffraction tomography is an indispensable tool for studying objects in three-dimensions due to its ability to accurately reconstruct scattering objects. Until now this technique has been limited to coherent light because spatial phase information is required to solve the inverse scattering problem. We introduce a method that extends optical diffraction tomography to imaging spatially incoherent contrast mechanisms such as fluorescent emission. Our strategy mimics the coherent scattering process with two spatially coherent illumination beams. The interferometric illumination pattern encodes spatial phase in temporal variations of the fluorescent emission, thereby allowing incoherent fluorescent emission to mimic the behavior of coherent illumination. The temporal variations permit recovery of the propagation phase, and thus the spatial distribution of incoherent fluorescent emission can be recovered with an inverse scattering model.
