Abstract
In a polarization-sensitive optical coherence tomography system, an interferometer includes single mode fibers and a plurality of polarization controllers. At least one of the plurality of polarization controllers is disposed on each of the fibers of the interferometer. The fibers include a fiber for sample light beam, a fiber for reference light beam, and a fiber for detection light beam. An image forming unit determines a pixel value from a data set consists of two orthogonal polarization components simultaneously obtained at substantially identical spatial positions of a test sample, wherein a measurement light beam has static single polarization state.
