Abstract
Polarization measurement is a technique that investigates the polarization state of light by measuring the vibration direction of light waves, obtaining information about materials, structures, or the interaction between light and substances. It finds extensive applications in various fields such as astronomy, remote sensing, and target detection. Most current polarimeters in use require moving components and involve multiple measurement steps. To address these shortcomings, this paper proposes a polarization polarimeter with a split-pupil design based on the combination of a quarter-wave plate and a liquid crystal polarization grating. This configuration allows the polarimeter to obtain the complete set of linear Stokes parameters in a single exposure. Therefore, it has high detection efficiency. The polarimeter has no mechanical moving parts and features a compact structure., This technique can play an important role on polarization measurement instruments.
