In an optical diffraction microscopy experiment, one measures the phase and amplitude of the field diffracted by the sample and uses an inversion algorithm to reconstruct its map of permittivity. We show that with an iterative procedure accounting for multiple scattering, it is possible to visualize details smaller than lambda/4 with relatively few illumination and observation angles. The roles of incident evanescent waves and noise are also investigated.
在光学衍射显微镜实验中,人们测量由样品衍射的场的相位和幅度,并使用反演算法来重建其介电常数分布图。我们表明,通过考虑多次散射的迭代过程,有可能用相对较少的照明和观察角度来可视化小于λ/4的细节。还研究了入射倏逝波和噪声的作用。
