Approach to fiber-based optical polarimetry for tissue assessment: system calibration and application

The potential of optical polarimetry is increasingly explored to unravel the tissue structure through several optical instrument configurations. Fiber-based solutions offer portability and are accommodative in an endoscopic examination environment. Here, we address the challenges in realizing a fiber-based optical polarimetry system through an approach involving an all-fiber polarization controller. The methods of device calibration and application in bulk tissues are discussed, and results are presented.
