Abstract

In this research, we propose a demodulation algorithm for the dual rotation polarizer-analyzer polarimeter. The proposal retrieves the partial Mueller matrix from the complex coefficients, theoretically calculated from the Fourier transform of the output intensity. As calibration parameters, the initial orientations of the polarizer-analyzer are used. Experimental results for air and a rotating dichroic film polarizer show our proposal's feasibility.
