Polarization measurement using polarization interference imaging spectrometer

Abstract

It is a common method to use the interferential characteristics of light to detect the object in the polarization interference imaging spectrometer system，but the polarized characteristics are usually ignored. In this paper, an advanced way, which combines the basic theories of polarization interference imaging spectroscopy and polarization measurement technology, is studied and used to detect the polarization parameters (e.g. degree of polarization, azimuth angle of polarization), and the error is analyzed, which proves that the system is very stable and precise in theory. Now the polarization interference imaging spectrometer can be used not only as cameras and interferometers but also as polaristrobometers, because the polarized characteristics of the light are made good use of to analyse and distinguish the object in a new way.
