Abstract
In this work, a simplified cylinder-birefringence optical model of the human skin dermis model is reported. The actual polarization parameters of human fingernail skin were measured. And the accuracy and stability of the Mueller matrix polarization decomposition (MMPD) and the direct Mueller matrix (DMM) methods were compared under different incident and scattering angles. One main novelty of the present work is that the value of birefringence of the skin dermis was obtained from images of living human index finger nails by using a polarization-sensitive optical coherence tomography device. The results obtained in this work provide a basis for the selection of incident and scattering angles when measuring biological samples containing fibrous structures in the future.
