Error mapping in DOFP Stokes images and its use for retardance calibration
Résumé
Division of Focal plane imagers have recently been developed for polarimetric imaging. Those sensors use a grid composed of four different pixels with four different polarizers engraved on them. Four of these different pixels form a superpixel which enables the estimation of the linear Stokes vector with a single acquisition. Those sensors are particularly sensitive to the spatial variations of the scene. Therefore, if such variations are non-negligible compared with the measurement noise, the estimation of the state of polarization is corrupted. We propose a method to map the superpixels in which the estimation can be trusted.
