The monochromatic images acquired form what we call a hyperspectral data cube, which contains both the spatial and spectral information of a sample. In the hyperspectral cube, the first two dimensions are spatial (x,y axis) while the third dimension (z axis) is the wavelength. Depending on the size of the sensor used, one single cube can represent many gigabytes of data representing an extremely rich source of information for material scientists or biomedical researchers. This data can be analysed using our proprietary software, PHySpec™.
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 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.
