摘要：

Differential phase contrast optical coherence tomography (DPC-OCT) can image small phase differences occuring between beams that penetrate a sample at closely spaced areas. Such phase differences can be caused by regions of slightly varying refractive index. We report on two recent improvements of this technique: we demonstrate depth resolved differential phase imaging in a transparent multi-layer sample. Furthermore, we report on a modified setup designed for phase imaging in scattering samples and demonstrate first results.
