A novel LED based light source with a high degree of modularity is resented as a means of illumination in a hyperspectral imaging system, employing multiple LED panes with different wavelengths. We report on first results and experience gained using such illumination in a large area hyperspectral imaging system.
Curvature and height corrections were made on hyperspectral images in order to reduce intensity dependence on distance and inclination. The corrections were made by Lambertian cosine law and measured 3D surface of the sample. Image of homogeneous phantom appeared significantly more homogeneous after correction.
