Abstract

Hyperspectral sensing opens up great possibilities for future remote sensing. In particular, high-resolution hyperspectral analysis will be an indispensable tool for agricultural applications, hydrodynamics and ocean physics, and polarimetric analysis of solar radiation reflected from rivers, lakes and marshes is expected to play an important role in environmental observation. In conventional multispectral analysis, detailed information has not been able to be used because each pixel includes much mixed spectral radiometric information, so it is difficult to obtain high classification accuracy in the analysis. To address this problem, the authors have been investigating some experimental analysis schemes using a hyperspectral imaging spectropolarimeter with selectable plane of polarization developed by the Japan Aerospace Exploration Agency (JAXA), and these investigations have yielded some remarkable results in the observation of polluted water in laboratory models and field experiments. These results indicate the possibility of applying the imaging spectropolarimeter to wide area environmental observation. This paper describes preliminary experiments for detecting concentration of suspended solid in water using the hyperspectral imaging spectropolarimeter with multi-polarization. Several hyperspectral analysis schemes for detecting such water pollution and analysis results of the observation data are presented.
