摘要
偏振成像技术作为一种前沿的成像技术,在近些年来发展迅速.相比于传统的成像技术,偏振成像技术在提供二维空间光强分布的基础上,增加了偏振维度的信息,提高了成像的准确度.本文对附着水滴光学窗口模型开展偏振成像特性的研究,用蒙特卡洛光线追踪法完成了数值模拟,用Stokes矢量记录偏振维的信息,分析了光源类型、水滴直径和水滴接触角对成像效果的影响规律,对提高成像质量具有重要意义.
Abstract
The polarization imaging technology,as a cutting-edge imaging technology,has de-veloped rapidly in recent years.Compared with traditional imaging technologies,the polarization imaging technology provides two-dimensional spatial light intensity distribution,increases the po-larization dimension information and improves the accuracy of imaging.This paper investigates the polarization imaging characteristics of optical windows with condensed droplets.The Monte Carlo ray tracing method is used to complete the numerical simulation,and the Stokes vector is used to record the information of the polarization dimension.The influence rule of the type of light source,droplet diameter and droplet contact angle on the imaging effect is analyzed,which is of great significance for improving the imaging quality.
