Abstract

An imaging, variable-retardance, Fourier-transform spectropolarimeter is presented that is capable of creating spectropolarimetric images of scenes with independent characterization of spatial, spectral, and polarimetric information. The device has a spectral resolution of approximately 225 cm(-1), making it truly hyperspectral in nature. Images of canonical targets such as spheres and cylinders obtained in a laboratory setup are presented. The results demonstrate the capability of developing systems to collect spectropolarimetric data of field images by use of the concept of pushbroom scanning and serial collection of polarimetric information. Further development of a parallelized collection strategy would allow the collection of near-real-time images of real-world targets.

摘要

本文介绍了一种成像可变延迟傅里叶变换光谱偏振仪，它能够创建具有空间、光谱和偏振信息独立表征的场景光谱偏振图像。该设备的光谱分辨率约为225 cm(-1)，本质上是真正的高光谱设备。文中展示了在实验室设置中获得的球体和圆柱体等典型目标的图像。结果表明，利用推扫式扫描概念和偏振信息的串行采集，有能力开发系统来收集野外图像的光谱偏振数据。进一步开发并行采集策略将允许收集现实世界目标的近实时图像。
