Abstract

A novel dual angle optical coherence tomography (OCT) method is developed that has been termed stereoscopic OCT, highlighting the similarities between this technique and stereoscopic ranging. OCT images are obtained at two angles of incidence with respect to the surface of a layered phantom. From these measurements, optical path lengths are determined for each layer that are used to calculate the refractive index and physical thickness of each layer directly from Snell's law. This method may prove to be useful for characterising the bulk optical properties of biological material in vivo, that are presently not well known or understood.
