摘要：

We describe a full-field optical coherence tomography (OCT) system for extracting 2D cross-sectional images from a multiple-layer information carrier. A simple and practical method is used to remove the fringes in the extracted cross-sectional interference images. To the best of our knowledge, for the first time, the inter-layer-modulation effect of 2D OCT is proposed and analyzed. The related algorithms for de-modulation and image enhancement are formulated. This system has the potential to be used for document security and object identification. Crown Copyright (C) 2004 Published by Elsevier B.V. All rights reserved.
