摘要:
An optical system for the tracking or verification of items, having an energy source (e.g., an illumination source), selectively producing a specific wavelength (or small set of wavelengths, such as a spectrum) of energy matched with a material sensitive to that illumination. When the material is subjected to the energy source, it emits a wavelength of energy which is then sensed by a detector.
