提出了一种用于相干显微镜的大口径电磁模型，解决了反散射问题。对模型进行了近焦和远焦操作的近似。这些近似结果产生了与干涉合成孔径显微镜（ISAM）一致的图像重建算法：这验证了ISAM在矢量设置中处理光学相干层析成像和光学相干显微镜数据。数值模拟证实，在焦平面外可以实现衍射极限分辨率，而焦深仅受测量噪声和/或探测器动态范围的限制。此外，所提出的模型适用于在第一个玻恩近似内工作的偏振相干显微镜系统的定量研究。(c) 2007年美国光学学会。
A large-aperture, electromagnetic model for coherent microscopy is presented and the inverse scattering problem is solved. Approximations to the model are developed for near-focus and far-from-focus operations. These approximations result in an image-reconstruction algorithm consistent with interferometric synthetic aperture microscopy (ISAM): this validates ISAM processing of optical-coherence-tomography and optical-coherence-microscopy data in a vectorial setting. Numerical simulations confirm that diffraction-limited resolution can be achieved outside the focal plane and that depth of focus is limited only by measurement noise and/or detector dynamic range. Furthermore, the model presented is suitable for the quantitative study of polarimetric coherent microscopy systems operating within the first Born approximation. (c) 2007 Optical Society of America.
