Correct interpretation of image contrast obtained with full-field optical coherence tomography (FFOCT) technique is required for accurate medical diagnosis applications. In this work, first, the characteristics of microscopic structures of tissue that generate the contrast in en-face tomographic image obtained with FFOCT are discussed. Then an overview is given of the parameters that affect image contrast. Finally, the contrast correction factor for correct image interpretation and the contrast limits to practical FFOCT systems are outlined.

“…Recently, a few papers have also appeared on the polarization changes of laser beams in oceanic turbulence and biological tissues. [11][12][13][14] It was found that even though the power spectrum of refractive index fluctuation has a very similar structure for random media, the polarization characteristics of beams traveling in these media are qualitatively different. To the best of our knowledge, only Gaussian Schell-mode beams and partially coherent radially polarized doughnut beams passing through oceanic turbulence have been studied.…”

Changes in polarization properties of partially polarized, partially coherent vectorial cosh-Gaussian (ChG) beams propagating in oceanic turbulence are studied with the unified theory of coherence and polarization. Numerical examples of changes in optical intensity and polarization properties such as the degree of polarization, orientation angle, and degree of ellipticity of the beam propagating in the turbulent ocean are given. We find that both parameters of the source and oceanic turbulence have an effect upon the polarization properties of the beam. The degree of polarization fluctuates when the ChG beam propagates in the oceanic turbulence, and it has an obvious reconstruction phenomenon in the far-field zone.

“…Chen and Li have been researched the coherence properties and polarization modulation of QH beams scattered from anisotropic media [4][5]. The propagation properties of laser beams in random media like turbulence or human tissue are important for applications such as optical imaging, remote sensing and communication systems so more and more researchers are attracted [6][7][8][9][10][11]. The polarization "self-reconstructed" phenomenon in atmosphere turbulence has been known for a long time.…”

Based on the extended Huygens-Fresnel principle and generalized Stokes theory, the evolution of polarization properties of beams generated by quasi-homogenous (QH) sources propagating in clear oceanic water was studied by the use of the oceanic turbulence spatial spectrum function. The results show that the beams have similar polarization self-reconstructed behavior under different turbulence conditions in the far field, but if the propagation distance is not long enough, the degree of polarization (DOP) fluctuates with much more complexity than state of polarization (SOP) of QH beams. The self-reconstructed ability of DOP at the special distance in turbulence would get to the best value if the values of coherence of width were chosen suitably, but for SOP, it has no best value.
