Abstract

Optical coherence tomography (OCT) is a new imagin modality capable of recording cross-sectional images of transparent and semi-transparent structures with a resolution on the order of 10 micrometers . Classical OCT imags the distribution of backscattering and -reflecting sites within the sample. However, as is known from microscopy, many objects yield only a poor image contrast if imaged on a pure intensity basis. These objects may, however, change other properties of the light which can be used for improving the image contrast. This forms the basics of advanced optical contrast enhancement techniques. We report on recent results were obtained with two of these techniques: polarization sensitive OCT and differential phase contrast OCT.
