Contrast phantoms for optical coherence tomography

摘要

In this work we present contrast measurement phantoms for optical coherence tomography. In this initial study, contrast has been evaluated from OCT images of a USAF-1951 bar target, buried beneath scattering layers of different density.Preliminary results indicate that scattering does not degrade imaging contrast significantly, however further work is required to verify these findings. This work has important implications from a quality control perspective as well for OCT inter-comparisons at, for example, different wavebands.
