Optical coherence tomography (OCT) is a powerful tool for three-dimensional (3D) and non-invasive investigation of eye. Polarization sensitive OCT (PS-OCT) is an extension of OCT and which provides birefringence tomography of in vivo tissue. The tissue birefringence is known to be strongly related to the microscopic structures of the tissue, and hence it is useful for tissue contrast imaging.
A new polarization-sensitive optical coherence tomography (PS-OCT) system is proposed for obtaining simultaneous measurements of the thickness, mean group refractive index, apparent phase retardation, and optical axis orientation of a linear birefringent material. The proposed PS-OCT system has no need for a high-precision scanning stage or controller and utilizes a thermal light source in order to...
