Ambient reflectivity absorption system for identifying precious or semi-precious materials and associated methods

摘要

A reflectivity absorption system for identifying a target precious or semi-precious material can include a detector, a filter system, and an output display. The detector system is capable of detecting a reflected electromagnetic radiation at a primary wavelength and a secondary wavelength. The reflected electromagnetic radiation can be produced from sunlight or other light source. The primary wavelength corresponds to an upper reflectivity of the target material while the secondary wavelength corresponds to a lower reflectivity of the target material. Reflectivity is a function of wavelength such that identifiable variations in wavelength can be observed for certain materials over specific wavelength ranges which are then compared to a known standard reflectivity response for the indicated wavelengths. These systems can be used in portable, handheld, or stationary configurations and can identify exposed target materials in real-time.

1. A reflectivity absorption system for identifying a target material, comprising:
a) a detector system capable of detecting a reflected electromagnetic radiation at a primary wavelength and a secondary wavelength, said reflected electromagnetic radiation deriving from reflection of electromagnetic radiation from a sample surface, said primary wavelength corresponding to an upper reflectivity of the target material and said secondary wavelength corresponding to a lower reflectivity of the target material; b) a filter system operatively connected to the detector and configured to filter the reflected electromagnetic radiation into an upper spectral region and a lower spectral region, said upper spectral region encompassing the primary wavelength and excluding the secondary wavelength, and said lower spectral region encompassing the secondary wavelength and excluding the primary wavelength; and c) an output display configured to register an output signal in a viewable format, said output signal formed using the upper and lower spectral regions.
