Abstract

We developed a novel fiber-based minimalistic system for cross-polarization optical coherence tomography using polarization-maintaining fiber in the sample arm. A long section of polarization-maintaining fiber was placed in the sample arm which acted as a delay line. Co- and cross-polarized images appear at different depth positions within the image. Test measurements with a quarter-wave plate demonstrate the sensitivity of the system to the birefringence of the sample. The signal in the images is not sensitive to the bending of polarization maintaining fiber in the sample arm, making the system a promising tool for endoscopy and clinical applications.
