正交扫描差分相衬光学相干层析成像的定量相位重建

Quantitative phase reconstruction for orthogonal-scanning differential phase-contrast optical coherence tomography

Bettina Heise, David Stifter

摘要:

我们提出了差分相衬光学相干层析成像(DPC-OCT)与两个横向分离的探测光束,通过采用可旋转的Wollaston棱镜感测在各个方向上的相位梯度。结合基于正则化阴影恢复形状(SfS)方法的二维数学重建算法,可以从一组两个正交的正面DPC-OCT图像确定精确的定量相位图,如在各种技术样品上例示的。

英文摘要:

We present differential phase-contrast optical coherence tomography (DPC-OCT) with two transversally separated probing beams to sense phase gradients in various directions by employing a rotatable Wollaston prism. In combination with a two-dimensional mathe- matical reconstruction algorithm based on a regularized shape from shading (SfS) method accurate quantitative phase maps can be determined from a set of two orthogonal en-face DPC-OCT images, as exemplified on various technical samples.
