ABSTRACT:
In an optical tomography system, an interference light obtained by multiplexing the reflected light from the object and the reference light is guided to an interference light detecting means by a waveguide means. The interference light detecting means has a spectrometer spectrally dividing the interference light. A polarization setting means which causes the interference light guided by the waveguide means to enter the spectrometer after setting the state of polarization of the interference light guided by the waveguide means to a predetermined state of polarization is provided between the waveguide means and the spectrometer.
