Abstract

In this talk, a spectral domain polarization sensitive optical coherence tomography (SDPS-OCT) system has been developed so as to obtain high scan speed, high dynamic range and high sensitivity, and simultaneously get birefringence contrast of some biological tissue. To reduce corruption of the DC and autocorrelation terms to images, we introduce the two phase method. The stocks vectors (I, Q, U, and V) of the backscattered light from the specimen have been reconstructed by processing the signals from the two channels which are responsible for detecting the vertical and horizontal polarization state light separately. Further, the phase retardation between the two orthogonal polarization states has been acquired. The results from rabbit eye show that SDPS-OCT system based on the two phase method has great potential to imaging biological tissue.
