使用数字傅里叶显微术的光学散射成像

Optical scatter imaging using digital Fourier microscopy

摘要:

最近由Alexandrov等人报道的关于光学散射成像的方法,称为数字傅立叶显微术(DFM),代表了数字傅立叶全息术对生物物质的选择性成像的适应。记录样品光散射的全息模式使得能够重建样品图像。样品成分的形状因子提供了在后处理阶段通过灵活的数字傅立叶滤波来实现这些成分的辨别的基础。像在暗场显微镜,DFM图像的对比度似乎改善由于抑制从扩展的样品结构的光学散射。在本文中,我们提出了理论和实验研究的DFM使用生物体模,其中包含多态散射。

英文摘要:

An approach reported recently by Alexandrov et al. on optical scatter imaging, termed digital Fourier microscopy (DFM), represents an adaptation of digital Fourier holography to selective imaging of biological matter. Holographic mode of recording of the sample optical scatter enables reconstruction of the sample image. Form-factor of the sample constituents provides a basis for discrimination of these constituents implemented via flexible digital Fourier filtering at the post processing stage. Like in the dark-field microscopy, the DFM image contrast appears to improve due to the suppressed optical scatter from extended sample structures. In this paper, we present theoretical and experimental study of DFM using biological phantom that contains polymorphic scatterers.
