We have developed a reflection tomographic microscope in which the sample is reconstructed from different holograms recorded under various angles and wavelengths of incidence. We present an iterative inversion algorithm based on a rigorous modeling of the wave-sample interaction that processes all the data simultaneously to estimate the sample permittivity distribution. We show that using several wavelengths permits a significant improvement of the reconstruction, especially along the optical axis.
我们开发了一种反射层析显微镜，其中样本是根据在不同入射角和波长下记录的不同全息图进行重建的。我们提出了一种基于波与样本相互作用的严格建模的迭代反演算法，该算法同时处理所有数据以估计样本介电常数分布。我们表明，使用多个波长可以显著改善重建效果，尤其是在光轴方向上。
