System and method for authenticating and classifying products using hyper-spectral imaging
In some implementations, a method for authenticating and classifying a set of materials comprises: transmitting a visible range light from a light source toward a vessel containing a material sample; wherein the visible range light passes through the vessel containing the material sample, passes through the material sample, and bounces off a HOE located at a bottom of the vessel toward a camera implemented in a smartphone; receiving, by the camera of the smartphone, the visible range light that bounced off the HOE; based on a mapping of each of the visible range light onto an area of an 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 image sensor's area.
