Abstract: This paper proposed a novel polarimeter for full-Stokes polarization imaging without using any kind of micro-polarizer array. The key components of the polarimeter are two grooved birefringent crystal plates with deviate fast axis, which are called Binary Birefringent Crystals (BBCs) in this paper. Mounting the jointed BBCs in the focal plane of an imaging detector, we manage to obtain the four components of Stokes vector simultaneously through the method proposed in this paper. We demonstrate the basic principle of the proposed polarimeter and verify it through numerical analysis. And one of the best-optimized configurations for the polarimeter is also presented. The proposed polarimeter is simultaneous, compact, easier in fabrication and capable of full-stokes polarization imaging. It is expected to be of potential use in a variety of applications.
