Abstract

The underwater optical polarization imaging with active light source illumination is studied. The mechanism and modeling of active polarization detection process with the linear polarization are demonstrated through theoretical and experimental analysis. The corresponding experiments were carried out for different objects with different distances and materials in water with different turbidity. In particular, the imaging effects with different wavelengths of light sources were compared at low turbidity, the imaging effects with 532 nm wavelength light are better than that of 633 nm wavelength. These results may benefit the underwater optical polarization imaging for achieving more diversified and flexible functions.
