1. A method for authenticating and classifying a set of materials, the method comprising:
determining a set of characteristics of light spectra reflected or transmitted by a set of materials when the set of materials is illuminated by a plurality of light wavelengths;
constructing one or more classifiers configured to classify each material of the set of materials based on the set of characteristics of the light spectra;
using the classifiers to classify, mapping each of the light spectra onto an area of an image sensor;
based on the mapping of each of the light spectra onto the area of the image sensor, generating a holographic optical element that has a plurality of regions, that receives input light reflected or transmitted through a new material, and that filters the input light to a filtered light by each characteristic light spectra, and mapping the filtered light onto the area of the image sensor;
wherein the holographic optical element is recorded and used to determine whether the new material matches any material in the set of materials.
