摘要：
A new model of Fourier domain optical coherence tomography (FDOCT) is proposed, valid within the first Born approximation, which takes the fluctuations of the dielectric susceptibility of tissue into account. It is shown that the spectral electrical power at the detector in the FDOCT system is proportional to the Fourier component of the spatial correlation function of the dielectric susceptibility of the tissue, proportional to the squares of the spectrum of the incident light field and the amplitude reflectance of the reference mirror. One possible application of the obtained result is to use the measured spectral data of the spatial correlation function of the dielectric susceptibility to quantitatively characterize properties of tissue.
