Abstract
A method to obtain and process data to generate intrinsic hyper-spectral data cubes is provided, where a data acquisition procedure involves scanning the field of view under focused and diffused conditions and an intrinsic calibration procedure requires focused and diffused scans of the field of view of a white reference surface. The spectra of the diffuse scan of the white reference surface is subtracted from the spectra of the focused scan of the white reference surface resulting in a residual data cube of a scan of the white surface. To obtain an intrinsic data cube of a field of view of interest, the residual data cube is added to the diffused data cube of the field of view of interest generating a resulting data cube that is subtracted from the focused data cube field of view of interest.
