Abstract

Disclosed are hyperspectral/multiple spectral imaging methods and devices. A method obtains first and second spectral image datasets of a region of interest (ROI). The first spectral image dataset is characterized by a first spectral range and the second spectral image dataset is characterized by a second spectral range. The method then performs a first spectral analysis on the first spectral image dataset and a second spectral analysis on the second spectral image dataset. Afterwards, the method determines one or more spectral signature(s) at a deeper layer of the ROI.
