1. A polarization sensitive optical coherence tomography (OCT) system, the system comprising:

  • a light source;

    a differential path interferometer comprising;

    a sample arm comprising a first circulator coupled to a sample via a first single mode optical fiber, the sample coupled to a probe via a second single mode fiber, wherein both the first single mode fiber and the second single mode fiber are not connected to a polarization controller, and wherein the first circulator is connected to a coupler via a third single mode fiber; and

    a reference arm comprising second circulator coupled to a variable delay line via a first polarization maintaining optical fiber, and wherein the second circulator is connected to the coupler via a second polarization maintaining fiber;

    a splitter configured to split light from the light source to the sample arm and the reference arm; and

    at least one detector.
