Fourier-Domain Optical Coherence Tomography Signal Analysis and Numerical Modeling

Figure 6

Schematic of the construction of the OCT phase in the -domain. The OCT signal is represented by the long arrow. A single noise realization is represented by the short arrow and is a vector from the Gaussian distributed noise around the origin. The OCT signal including the noise is constructed from the vectorial addition of the two contributions and leads to the variation of the angle .
