Model for the depolarizing retarder in Mueller matrix polarimetry

We advance an analytical model describing the polarimetric response of a depolarizing retarder whose retardance varies spatially in magnitude or in orientation. The variation of the retarder parameters may be either of deterministic or of random nature. The model provides both the mean values and the uncertainties of the parameters. Its application is illustrated on two experimental examples, respectively covering the deterministic and the random cases. ?? 2022 Optica Publishing Group

Automated summary

An analytical model describing the polarimetric response of a depolarizing retarder with spatially varying retardance is presented, considering deterministic or random variations in the retarder parameters. The model provides mean values and uncertainties of the parameters, and its application is illustrated with experimental examples covering both deterministic and random cases.
