Hyperspectral camera with polarized filter as modern supersensor device for cyber-physical systems

摘要

Starting from 2008-2010, the hyperspectral cameras have become very popular supersensor devices capable to record spectral information for every pixel of the observed view field. Those cameras can be applied in numerous application fields where human eye is not able to distinguish between the different spectral signatures. The article describes measurements of natural forest background, dry hay ground, military vehicle and compares reflection of dry, wet and frozen road surfaces. As a special advanced feature, the experiments with linear polarization filter are presented and analyzed. Article offers a simple formula based analytical model of a the pine forest “700 nm red step” and “near infrared plateau”.
