Optical diffraction tomography is an imaging technique that permits retrieval of the map of permittivity of an object from its scattered far field. Most reconstruction procedures assume that single scattering is dominant so that the scattered far field is linearly linked to the permittivity. In this work, we present a nonlinear inversion method and apply it to complex three-dimensional samples. We show that multiple scattering permits one to obtain a power of resolution beyond the classical limit imposed by the use of propagative incident and diffracted waves. Moreover, we stress that our imaging method is robust with respect to correlated and uncorrelated noise.
光学衍射层析成像术是一种成像技术,它能够从物体的散射远场中获取该物体的介电常数分布图。大多数重建过程都假定单次散射占主导地位,这样散射远场就与介电常数呈线性关联。在这项工作中,我们提出了一种非线性反演方法,并将其应用于复杂的三维样本。我们表明,多次散射能够使分辨率超越使用传播的入射波和衍射波所带来的经典极限。此外,我们强调我们的成像方法对于相关噪声和不相关噪声都具有鲁棒性。
