This paper presents a hand-held single-mode fiber-based polarization-sensitive optical coherence tomography (PS-OCT) system with a single input polarization state. One drawback of this system is that the polarization becomes arbitrary, which can be solved by placing a polarization controller in the sample arm. A calibration target with an azimuthally varying optic axis integrated with the handheld probe will provide an absolute orientation axis measurement. This significantly reduces cost, time and availability of PS-OCT for clinical applications. With the home-built PS-OCT, we investigate the reorganization of collagen and blood vessel in a wound on the dorsal side of the human hand.
