Abstract
A system and method for detecting a contaminant in a sample. The contaminant may comprise melamine or a derivative thereof and the sample may comprise a feed material. The method may comprise illuminating a sample to thereby generate a first plurality of interacted photons, collecting the interacted photons, passing the interacted photons through a tunable filter, and detecting the interacted photons to generate a near infrared data set representative of the sample. This near infrared sample may comprise a hyperspectral near infrared image. The method may further comprise fusing said near infrared data set with a Raman data set representative of sample. A system may comprise an illumination source, one or more collection optics, a tunable filter, and a detector configured to generate a near infrared data set. The system may further comprise a second detector configured for generating a Raman data set representative of a sample.
