对于动物组织的透光成像，我们开发了一种利用相位共轭光的时间反转原理来抑制混浊介质中的散射效应的技术。在这项技术的生物医学应用中，必须阐明吸收变化和适用的组织厚度的影响。对实验数据的分析表明，该技术的散射抑制能力与混浊介质的吸收变化无关。结果还证实，使用具有更大相干长度的光源可以扩展动物组织的适用厚度。
For transillumination imaging of animal tissue, we have developed a technique to suppress the scattering effect in a turbid medium using the time-reversal principle of phase-conjugate light. In biomedical applications of this technique, the effects of absorption variation and the applicable tissue thickness must be clarified. Analysis of experimental data revealed that the scattering suppression capability of the proposed technique is independent of the absorption change of a turbid medium. Results also verified that the applicable thickness of animal tissue can be extended using a light source with greater coherence length.
