Abstract

Time-division-detected fiber-optic Mueller OCT system was developed for radiumdium. In this system, Mueller matrix was used to measure the polarization characteristics of the anisotropic scattering medium. There are four optical channels for different polarization types in reference arm: horizontal , vertical , 45° linearly polarized , and circular polarization. Meanwhile the sample arm uses rotary wave plate to achieve the four polarizations of light. The optical switches are used to select different channels in the reference arm, and the polarized light of each channel interfere with the polarized light backscattering from the sample. Therefore, the sixteen OCT images from different polarization were obtained to calculate Mueller matrix of sample. Finally, this OCT system was applied for quantitatively characterize isolated pig myocardium structure.
