Abstract

The degree of linear polarization (DOLP) expressions at any polarizer direction (PD) was deduced based on the Stokes vector and Mueller matrix. The average gray level range of the target units (20x20 pixels material) under triple-waveband and low illumination condition was obtained with 46 kinds of experimental materials. This paper mainly explored that the influence factors of the error and stability of multi-PD DOLP was researched by the numerical analysis, and outdoors experiments were carried out to demonstrate the analysis method. Studies have shown that when detection angle was near specular reflection direction, when interval angle of PD between angle A and angle B, between angle A and angle C were set as the range (40°≤Φ_AB ≤80°, Φ_AC =2.06Φ_AB), the standard deviation of DOLP was lower, but also polarization information obtained under low illumination condition was stable, and the numerical analysis was consistent with the experimental results.
