We optimize a general class of complete multispectral polarimeters with respect to signal-to-noise ratio, stability against alignment errors, and the minimization of errors regarding a given set of polarization states. The class of polarimeters that are dealt with consists of at least four polarization optics each with a multispectral detector. A(More)
Geospatial co-registration is a mandatory prerequisite when dealing with remote sensing data. Interor intra-sensoral misregistration will negatively affect any subsequent image analysis, specifically when processing multi-sensoral or multi-temporal data. In recent decades, many algorithms have been developed to enable manual, semior fully automatic(More)
A robust method for the optical characterization of polarimeter optics for a complete, multispectral polarimeter is presented. The polarimeter optics consists of a waveplate, a polarizing filter, and a multispectral detector. The method employs a source of unpolarized light and a rotating polarizing filter and retrieves the retardance and the angle of the(More)
The effects of polarization, sea water salinity, and temperature on top of atmosphere radiances and water leaving radiances (WLRs) are discussed using radiative transfer simulations for MEdium resolution imaging spectrometer (MERIS) channels from 412 to 900 nm. A coupled system of an aerosol-free atmosphere and an ocean bulk containing chlorophyll and(More)
