Abstract: (1271 Views)
In a Fourier Domain Optical Coherence Tomography (FD-OCT) system, the refractive index profile is the contrast mechanism that allows one to determine the inner structure of the object. When the refractive index variations inside the object are small, FD-OCT can precisely reconstruct the object’s internal structure. With increasing the object’s refractive index and internal reflections, phantom interfaces are created in the final image that sometimes is hard to be differentiated with the real interfaces. In this article, we examine a two-layer object and show that when the refractive indices exceed 1.45, the FD-OCT imaging system is unable to interpret the real interfaces of the object.
