Crosstalk and noise in division-of-focal-plane polarimeters and polarization imaging applications

A modern division-of-focal-plane (DoFP) polarimeter is manufactured by integrating a pixelated microgrid polarizer array directly onto an image sensor. Recent advances in complementary metal oxide semiconductor (CMOS) technology have led to sensors with pixel sizes on the order of a micron, which greatly increases spatial crosstalk. This work develops the fundamental limitations of DoFP polarimeters due to noise and expands upon how spatial crosstalk affects the reconstruction of the Stokes parameters. Experimental data is presented confirming the presented mathematical model and further emphasizing the detrimental effects of crosstalk on estimation of relevant polarization parameters for biomedical applications using quantitative polarized light imaging. Also discussed is modeling for underwater geolocalization based upon polarized light fields.LimitedAuthor requested closed access (OA after 2yrs) in Vireo ETD syste
