Abstract

Abstract

This study proposes an active polarization imaging approach that utilizes laser illumination to tackle the issue of low target detection contrast in strong light backgrounds, which is a challenge in conventional photoelectric detection. The study examines the coupling relationship between the polarization characteristics of three typical target materials and the scattering angle of a laser beam. This is achieved by constructing a laser incident bidirectional reflection distribution model, a laser incident polarization bidirectional reflection distribution model, and a target surface polarization model of laser illumination. Backlight observation experiments are conducted in a controlled darkroom to verify the impact of the scattering angle of the laser beam on the polarization characteristics of the target. The experimental results show an 86.11% increase in target contrast for active polarization imaging under strong light background compared to traditional passive intensity imaging. Additionally, different target materials exhibit differing visible polarization characteristics under varying beam dispersion angles, with metallic materials is higher than that of non-metallic materials. This result aligns with theoretical analysis and support the advantages of active polarization imaging. The outdoor solar backlight observation experiment verifies the applicability of the research method in high-intensity light and long-distance settings. This study can lay a theoretical foundation for improving accurate target perception under a strong light background.
