Abstract

When measuring the Mueller matrix images of a sample with a GRIN lens, many Mueller matrix elements will be seriously distorted by the intrinsic birefringence of the GRIN lens. Imaging polarimeter measurements of GRIN lenses showed radially symmetric phase retardance polarization. We simulated the Mueller matrices of the GRIN lens with light of different incident angles, removed the polarization artifacts with the simulated results and recovered the polarization features of the sample. The results demonstrate the possibility of performing Mueller matrix measurements using endoscopes or other optical instruments with strong birefringence.
