摘要
空间信息、光谱信息和偏振信息的同步获取将获得更多易于区分目标的特征信息。针对传统光谱偏振成像技术需要动态调制、光通量低、光谱分辨率有限和解算复杂等问题, 提出了一种基于光纤传像束和像元级偏振探测器的成像新模式, 将光纤成像光谱技术和像元级偏振信息快速提取技术结合, 以快照式方式同步获取目标的二维空间信息、一维光谱信息和四个角度的偏振信息。结合系统模型, 搭建了实验装置, 获取了 430~630nm(光谱分辨率约 1nm)的 200个谱段 4个角度的光谱偏振图像, 以及每个谱段的偏振度和偏振角。验证了该系统的光谱偏振成像数据同步获取能力, 技术原理正确可行, 未来将在天文观测、大气探测和目标识别等领域具有较高的应用价值。
Abstract
The simultaneous acquisition of spatial information,spectral information and polarimetric information canobtain more characteristic information to distinguish targets. Aiming at the problems that traditional spectral polarizationimaging technology requires dynamic modulation,low luminous flux,limited spectral resolution and complicatedcomputation etc.,a new imaging mode based on imaging fiber bundles and pixel-level polarization detector is proposed.Combining the fiber-optic imaging spectroscopy and pixel-level polarization information extraction technology,the twodimensionalspatial information,one-dimensional spectral information and four Stokes polarized information of the targetcan be acquired in a snapshot mode. Combined with the system model,an experimental device is set up to obtain four-anglespectral polarization images of 200 spectral bands ranging from 430 nm to 630 nm(spectral resolution is about 1 nm),aswell as the degree of polarization and polarization angle of each spectral band. The system’s spectral polarization imagingdata acquisition capability,and the correctness and feasibility of the technical principle are verified. The technology hashigh application value in the fields of astronomical observation,atmospheric detection,target recognition and other fields.
