中文摘要：

针对传统光谱偏振成像系统普遍存在的系统结构复杂、需要动态调制、光通量低等问题,提出一种基于静态调制的光谱偏振成像系统,将静态调制偏振探测方法与Savart偏光镜干涉成像原理相结合,可在成像过程中实时获取目标的光谱信息和全部四个Stokes偏振信息。与传统系统相比较,该系统具有无运动部件、无需动态电控调制、没狭缝限制、光通量大等优点。介绍了系统组成和基本原理,搭建了实验装置,实验装置包括二次成像光学系统、偏振调制模块、干涉成像模块、CCD图像采集及数据处理模块等,成像谱段范围为可见光近红外（480~950nm）。利用实验装置对白板、飞机玩具模型进行了成像实验,验证了该系统的光谱偏振成像数据获取能力。对静态调制的偏振测量精度进行了验证,偏振测量统计误差小于5%。实验结果验证了系统原理的正确性和可行性,获取的光谱偏振成像数据在目标识别、目标分类、遥感探测等方面具有较高的应用价值。
