Abstract

In this study we analyze the effect of experimental errors on the optimization and calibration method of a Mueller matrix imaging polarimeter based on liquid crystal variable retarders. The study is carried out through numerical simulations, where the optimized Mueller matrix polarimeter is simulated considering misalignments of the polarimetric components, and variations in the induced retardance of the LCVRs. However, the final measurement error does not depend only on non-ideal elements, but also depends on the noise, in the irradiance measurements, and the accuracy of the calibration method. Thus, the eigenvalue calibration method is used in the simulations, including random variations in the irradiance matrix. The tolerances of the optimization and calibration method are analyzed, and the results are presented.
