“…The reflected light has various polarization directions due to the differences in roughness, therefore the target can be distinguished and highlighted from the background by imaging. As a powerful tool for information detection, polarimetric systems provide valuable additional information in many aspects including medical diagnosis [4][5][6][7], imaging in complex environments [8][9][10], astronomical observation [11,12], remote * Author to whom any correspondence should be addressed. sensing, and navigation [13,14].…”

A novel polarimetric imaging system is proposed, which is based on one CMOS camera and double-layer prisms pair (DLPP). Four polarizers, whose axes were set at different angles and affixed to the four prisms. The CMOS camera is used to simultaneously record the intensity of the light passing through the prisms with four specific polarization information. An algorithm is adopted to align and correct parallax to generate accurate Stokes parameters. Indoor and outdoor experimental performances verify the effectiveness and high measurement accuracy of the proposed system.
