Abstract
A method for authenticating an estimated age of an archaeological artifact is described. The method generally includes irradiating the artifact with laser light, measuring a fluorescence spectrum emitted from the artifact and determining whether the artifact's actual age is consistent with the estimated age based on the measured fluorescence.
Claims20
A method for authenticating an estimated age of an archaeological artifact, comprising:
- irradiating the artifact with laser light having an energy density of between about 25 watts per square centimeter and up to 6250 watts per square centimeter;
- measuring a fluorescence spectrum emitted from the artifact;
- and
- determining whether the artifact's actual age is consistent with the estimated age based on the measured fluorescence.

A system for debunking a purported age of an artifact, comprising:
- a laser configured to output light having an energy density of between about 25 watts per square centimeter and up to 6250 watts per square centimeter;
- a spectrometer configured for measuring fluorescence stimulated by laser light absorption of the artifact;
- and
- a computer configured to analyze the fluorescence measured by the spectrometer and determine whether the fluorescence measured meets a threshold amount;
- wherein the computer is configured to display whether the fluorescence measured meets a threshold amount and wherein the purported age of the artifact is debunked if the measured fluorescence does not meet the threshold amount.
2 more elements
A method for debunking a purported age of an artifact, comprising:
- determining the level of radiation damage in the surface of the artifact;
- and
- comparing the level of radiation damage in the surface with the level of radiation damage in a reference material;
- wherein the purported age of the artifact is debunked if the level of radiation damage in the surface of the artifact falls within a range determined by the reference material.
