Abstract
In this work, the four optimum azimuthal angles are determined for a full-Stokes scanning polarimeter comprising a rectangular prism, quarter-wave plate, and four linear polarizers. The determinant and condition numbers of the measurement matrix are used as objective functions in an optimization procedure. Illustrative examples with optimum angles and commonly used angles of linear polarizers are presented to evaluate the sensitivity of the polarimeter in estimating the incident Stokes vector, in error cases involving fluctuations in the detected flux and/or errors in the azimuthal angles of the linear polarizers. Our results show that optimum angles produce smaller errors than commonly used angles, when deriving the incident Stokes vectors.
