Spectroscopic Fourier domain optical coherence tomography

摘要

We present a new method to obtain additional spectroscopic information by analyzing conventional Fourier domain optical coherence tomography (FDOCT) data. Conventional FDOCT data are based on the analysis of backscattered light, while spectral FDOCT (SFDOCT) also evaluates the absorption characteristics of the different sample layers. This is a result of analyzing the peak shapes of the single, one dimensional depth profiles regarding their modification due to absorption characteristics of the sample layers. A concept for depth allocation of different absorption characteristics is discussed.
