Whole-field Mapping in Polarization's Studies by Use of Null Polarimetry

摘要

In this paper we describe whole-field polarimetric technique ,w hcih exploits principles of null-scheme and extends them to whole -field mapping of the measured parameters.Operational principle of the method and the instrument configration are presented. As any other null - arrangement, the technique is base don finding a set of azimuth angles for the elements, which comprise the polarimeter, such that the ligth flux falling on the detector is extinguished. A detailed description of measurement processing with the peculiarities of whole-field exploitation mode is suggested. Theoretical considerations are supplemented with the measurement examples.
