Underwater Dynamic Polarization-Difference Imaging with Greater Applicability.

Available polarization-difference imaging techniques face serious challenges in imaging speed and application range. To address these issues, this paper proposes an underwater dynamic polarization-difference imaging method with greater applicability. First, the intensity distribution of backscattered light is estimated via the Stokes vector. Afterward, the differential operation between the total intensity of light and the amplified estimation result of backscattered light makes clear imaging immediately accessible. Regardless of the movement states and polarization characteristics of the target, experimental results consistently demonstrate that the backscattered light can be eliminated to a great extent, and imaging quality and applicability are significantly enhanced. Meanwhile, the proposed method is immune to unexpected factors such as uneven illumination and has good stability. More importantly, there are also apparent advantages in terms of imaging time.
