Herve Hugonnet, Mahn Jae Lee, Yongkeun Park

摘要:

反卷积相位显微镜通过重建透明样品的透射相位或折射率,实现透明样品的高对比度可视化。在这里,我们提出了一种方法来扩展2D反卷积相位显微镜厚3D样品。通过仅测量优化照明模式下获得的四幅强度图像,即可获得样品在特定轴平面上的折射率分布。此外,可以使用不同的照明图案来测量样品的光学相位延迟。

英文摘要:

Deconvolution phase microscopy enables high-contrast visualization of transparent samples through reconstructions of their transmitted phases or refractive indexes. Herein, we propose a method to extend 2D deconvolution phase microscopy to thick 3D samples. The refractive index distribution of a sample can be obtained at a specific axial plane by measuring only four intensity images obtained under optimized illumination patterns. Also, the optical phase delay of a sample can be measured using different illumination patterns.
