像素偏振成像系统的耦合实现

通过将像素偏振片组阵列与CCD光敏元耦合对准，对像素偏振成像系统耦合技术进行了研究。针对偏振片组阵列与CCD尺寸不匹配的问题，采用多种工艺方法进行了加工处理，提出了完整的耦合对准工艺。文中研制的成像系统可以通过一片成像探测器同时获得4个不同偏振方向的斯托克斯分量，得到所拍摄物体的线偏振度图像和线偏振角图像，实现图像的偏振增强，经后处理形成所需要的偏振图像，有利于在复杂环境中获取目标信息。

Coupling implementation of pixel polarization imaging system

The coupling technology of the pixel polarization imaging system was studied by aligning the pixel polarizer array with the CCD photosensitive element. Aiming at the problem that the polarizer group array and CCD size do not match, a variety of process methods were used for processing, and a complete coupling alignment process was proposed. The imaging system developed in this paper can obtain four Stokes components with different polarization directions through one imaging detector. After operation and post-processing, it could also obtain the linear polarization image and the linear polarization angle image of the captured object, which realized the polarization enhancement of the image. The required polarization image facilitates the acquisition of target information in a complex environment.
