摘要/Abstract

摘要： 紫外偏振成像技术在痕迹检测、宇航探测等方面有着独特的优势, 然而目前已开展的研究主要针对紫外偏振成像技术和系统本身, 而针对紫外偏振成像系统定标方法的研究还相对缺乏。为了解决紫外偏振成像系统的定标问题, 利用自研的紫外偏振分时成像系统研究设计了一种系统定标实验方法。通过分析紫外偏振成像系统的设计原理, 开展定标实验, 实现了紫外偏振成像系统的辐射定标和偏振定标。测试结果表明, 定标后系统均匀性误差降至 1% 以下, 偏振度测量误差小于 2%, 满足系统定标精度要求, 验证了该定标实验方法的有效性, 对紫外偏振成像系统定标具有指导意义。

Abstract: Ultraviolet polarization imaging technology has unique advantages in trace detection and space exploration. However, the current research mainly focuses on the ultraviolet polarization imaging technology and the system, and the research on the calibration method of ultraviolet polarization imaging system is relatively lack. In order to solve the calibration problem of uv-polarization imaging system, a systematic calibration experimental method is designed by using the self-developed uv-polarization time-sharing imaging system. By analyzing the design principle of uv-polarization imaging system, the calibration experiment is carried out, and the radiation calibration and polarization calibration of uv-polarization imaging system are realized. The experimental results show that after calibration, the uniformity error of the system is reduced to less than 1% and the measurement error of polarization degree is less than 2%, which meets the requirements of system calibration accuracy. The effectiveness of the calibration method is verified, which is of signicance for the calibration of ultraviolet polarization imaging system.

Key words: ultraviolet polarization, imaging system, radiation calibration, polarization scaling
