Hyperspectral canopy measurements under artificial illumination
Abstract:Hyperspectral canopy reflectance measurements are usually obtained under ambient solar illumination. In some specific cases, however, the use of artificial light is preferred. This raises issues, since artificial light is usually non-parallel and non-homogeneous over the area and height profile of the target. This study therefore attempts to address the characteristics of artificial illumination and the consequences for remote sensing. A low-cost experimental setup is proposed to counter the main issues of using artificial light in hyperspectral research.
