System and method for authenticating and classifying products using hyper-spectral imaging

One or more non-transitory computer readable storage media storing one or more instructions which, when executed by one or more processors, cause the one or more processors to perform:

• 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;
• wherein one or more optical elements filter and focus the light spectra onto one or more elements of a detector array;
• wherein each optical element, of the one or more optical elements, focuses onto an area of the detector array;
• wherein the mapping is a 1:1 mapping;
• wherein each optical element, of the one or more optical elements, uses a Bragg reflection condition to filter the light spectra and to focus the light spectra onto an element of the detector array;
• wherein an amplitude of each element of the detector array is read and transmitted to a classifier software application;
• wherein the classifier software application determines a class of a material that is illuminated.

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 scattered from 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.
