Abstract

Division-of-focal-plane (DoFP) polarimeter, as a snapshot polarization imaging system, has significant advantages in detecting moving objects. However, the accuracy of DOFP polarimeter is fundamentally constrained by hardware limitations. This paper presents a novel polarization image restoration method based on sub-pixel segmentation with multi-decision specifically designed for liquid crystal micropolarizer arrays (LC-MPA) featuring large-scale sub-pixel structures. Experimental results demonstrate significant improvements over conventional methods, with quantitative metrics showing enhancements of 13.8 % in peak-signal-to-noise-ratio (PSNR), 21.2 % in structure similarity index measure (SSIM), and 64.2 % in enhancement measure by entropy (EME). This work provides a computationally efficient and cost-effective solution that advances the practical implementation of high-precision polarization imaging systems.

基于大规模亚像素分割的Full-stokes图像恢复方法

焦平面分割偏振仪作为一种快照偏振成像系统，在检测运动物体方面具有显著的优势。然而，DOFP偏振计的精度从根本上受到硬件限制。针对具有大规模亚像元结构的液晶微偏振器阵列（LC-MPA），提出了一种基于亚像元分割的多决策偏振图像恢复方法。实验结果表明，与传统方法相比，该方法具有显著的改进，定量指标显示峰值信噪比（PSNR）增强13.8%，结构相似指数（SSIM）增强21.2%，熵（EME）增强64.2%。这项工作提供了一种计算效率高、成本效益高的解决方案，促进了高精度偏振成像系统的实际实现。

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
