摘　　要：Compensation of polarization-variance-related artifacts is required to steadily obtain high-quality optical coherence tomography(OCT)images at various experimental conditions.Since most OCT systems utilize optical fiber to transfer the light easily and a polarized light source,the polarization state is arbitrarily changed in every different condition.In this study,we proposed polarization-maintaining-fiber-based polarization-insensitive OCT(PM-PI-OCT)with a simple optical configuration and a simple compensation process.The proposed PMPI-OCT is not only theoretically proved by mathematical derivations but also evaluated by quantitative analysis of various fiber twisting angles.Moreover,the applicability and robustness of the proposed PM-PI-OCT were proved by human retina imaging using the customized handheld probe.Our proposed polarization-insensitive OCT requires no pre-calibration,no post-processing procedure,and no computational load for implementation and is able to be applied to universal fiber-based OCT systems.We believe that our simple and robust polarization-insensitive OCT system is able to be applied to various existing OCT setups for polarization state variance compensation with high versatility and applicability.
