论文摘要
在这项工作中，我们考虑了从弹性学测量中重建分层介质的光学特性的反问题，其中光学相干断层扫描用作成像方法。特此，我们将样品建模为线性介电介质，以使成像参数由其电敏感性给出，这是频率和深度依赖性参数。除了分层结构（假定至少在小小的照明区域中是有效的），我们允许使用的小散射器，我们认为是随机分布的，与纯均匀层相比，这种情况似乎更现实。然后，我们表明，可以从光学相干断层扫描测量值来实现介质的敏感性（在小散射器上平均之后）的独特重建，以实现介质的不同压缩状态。
In this work we consider the inverse problem of reconstructing the optical properties of a layered medium from an elastography measurement where optical coherence tomography is used as the imaging method. We hereby model the sample as a linear dielectric medium so that the imaging parameter is given by its electric susceptibility, which is a frequency- and depth-dependent parameter. Additionally to the layered structure (assumed to be valid at least in the small illuminated region), we allow for small scatterers which we consider to be randomly distributed, a situation which seems more realistic compared to purely homogeneous layers. We then show that a unique reconstruction of the susceptibility of the medium (after averaging over the small scatterers) can be achieved from optical coherence tomography measurements for different compression states of the medium.
