Ghost polarimetry with unpolarized pseudo-thermal light

摘要

We present an experimental implementation of the ghost polarimetry concept in unpolarized light, which allows obtaining complete information on the spatial distribution of polarization properties of objects with linear dichroism. It is theoretically shown that it is possible to restore the spatial distribution of the azimuth and a value of anisotropy of such objects. The developed technique allows us to free up the object arm from all additional optical elements, including polarizers. The experimental results of measuring the dichroism parameters of a test four-sectional sample are presented, which demonstrate the efficiency of the method and confirm the correctness of the developed theoretical model.
