Abstract
An electronic device is for identifying the plastic composition of an unknown plastic object. The electronic device may include a spectrometer configured to receive the unknown plastic object and generate a MIR reflectance spectra characteristic of the unknown plastic object, a memory configured to store a multi-spectral fingerprint library for plastic types, and a processor coupled to the spectrometer and the memory. The processor is configured to analyze in real-time the MIR reflectance spectra characteristic of the unknown plastic object, and identify the plastic composition based upon at least comparing the MIR reflectance spectra characteristic of the unknown plastic object to the multi-spectral fingerprint library. The processor may be configured to expand the fingerprint library upon initial baseline characterization.
