我们证明了光传输矩阵（TM）提供了一个强大的工具来提取无序复杂介质的光子强度，独立于表面效应。我们测量TM的强散射GaP纳米线介质和比较的奇异值密度测量TM的随机矩阵为基础的波输运模型。通过改变模型中的输运平均自由程和有效折射率，我们反演了光子强度。从单独的数值模拟，我们得出结论，来自TM统计的光子强度是不敏感的样品的后表面的表面反射。
We demonstrate that optical transmission matrices (TMs) provide a powerful tool to extract the photonic strength of disordered complex media, independent of surface effects. We measure the TM of a strongly scattering GaP nanowire medium and compare the singular value density of the measured TM to a random-matrix-based wave transport model. By varying the transport mean free path and effective refractive index in the model, we retrieve the photonic strength. From separate numerical simulations we conclude that the photonic strength derived from TM statistics is insensitive to the surface reflection at rear surface of the sample.
