A system and method for optically identifying a product from a reference library of known products based on a reflected spectrum of the product. A broad wavelength light source illuminates the product and a spectrometer receives and forms a plurality of finely spaced wavelengths from the reflected spectrum. A detector optically processes the wavelengths to generate signals proportional to an amount of light received at each of the wavelengths. The signals are normalized and pre-processed to form data sets which relates each of the signals to each of the finely spaced wavelengths. This is performed for all of the different products and compiled. A set of basis functions is then generated for all of the different products and a corresponding set of basis coefficients is generated for each of the different products. This information, along with an electronic label for each product, is stored to form the reference library. When identifying an unknown product, the system generates a set of basis coefficients for the product to be identified. This latter set is statistically compared against the reference library to identify the corresponding set of basis coefficients most closely matching the unknown set of basis coefficients.
