Abstract:
1. A method comprising: illuminating a sample to thereby generate a first plurality of interacted photons and a second plurality of interacted photons; detecting said first plurality of interacted photons using a dispersive spectrometer to thereby generate at least one reference spectrum representative of said sample; passing said second plurality of interacted photons through a tunable filter; detecting said second plurality of interacted photons using an imaging detector to thereby generate at least one hyperspectral test image representative of said sample; assessing said test image to thereby determine a mean test spectrum wherein said mean test spectrum is representative of the mean intensity of a plurality of pixels in said hyperspectral test image; comparing said mean test spectrum to said reference spectrum to thereby determine an instrument response correction; and applying said instrument response correction to said hyperspectral test image.
