In this paper, we report results of a high precision polarization state measurement of light based on the in-plane spin splitting (IPSS) in optical reflection. The IPSSs in the coordinate (spatial) and momentum (angular) spaces are respectively highly sensitive to the polarization rotation and ellipticity of the incident light at the Brewster angle. By measuring both the spatial and angular IPSSs with different post-selections, the full information of the polarization state (polarization angle and ellipticity) of the incident light can be obtained. Our research may be applied for the precision measurement of polarization-dependent effects.
