Fig. 2. — Intensity signal and noise background in a schematic OCT depth profile. The noise floor is characterized by its average intensity $\bar{I_{n o i s e}}$ and its variance $σ_{I_{n o i s e}}^{2}$ . The measured OCT intensity signal $\bar{I}$ consists of the pure signal intensity $I$ biased by the average noise level $\bar{I_{n o i s e}}$ .
