"An imaging polarimetric slope sensing instrument for measuring water waves has been developed.\r\nFrom themeasurement of the intensities of three different linear polarization states,\r\nit is possible to determine the first three components of the polarization Stokes vector. The\r\nslope of the water surface is computed from the measurement of the polarization of reflected\r\nlight. Unlike in common polarimeters, custom optics are not required in this simple setup\r\nconsisting of three cameras aligned in parallel and each equipped with a standard polarization\r\nfilter. The trade-off for the simple setup is the need for more extensive system calibration\r\nand image post-processing. The camera setup was fully calibrated (extrinsic, intrinsic,\r\nand distortion parameters) with a specialized calibration procedure using a custom built target.\r\nThe analyzer matrix, which transforms the intensities of the measured polarization states\r\ninto the Stokes vector components was determined and verified experimentally. A data set\r\ncollected during an experiment on board the research vessel Meteor is analyzed. In an experiment\r\nat the Hamburgische Schiffsbau-Versuchsanstalt, the polarimeter was successfully\r\noperated under laboratory conditions. It is shown to be capable of measuring the slope distribution\r\nof mechanically generated waves. Elevation power spectra, determined by integration\r\nof the slope measurements, show good agreement with reference measurements with a wave\r\nwire. Deviations at low wave frequencies due the small size of the polarimeter footprint can\r\nbe compensated with a transfer function that is derived from the measurements."^^ . "2013" . . . . . . .
