Photon etc's Global Imaging Technology
This video shows the conceptual difference between hyperspectral global imaging and raster scan (line-scan, push- broom). With global imaging, the gain in acquiring 3D data, 2D spatial and 1D spectral, is important since the only a few monochromatic images are required to cover the complete spectral range where one needs to take the full spectrum for each point or line in the image with other technologies.
