Patent ID: 7379177

Claim:
A method to inspect glass object for a hardness characteristic parameter, said method comprising: measuring an incident intensity level of electromagnetic energy of at least two wavelengths emitted from at least one electromagnetic source at a predefined distance from said at least one electromagnetic source using at least one electromagnetic detector positioned at said predefined distance from said at least one electromagnetic source; positioning said glass object in proximity to said at least one electromagnetic source such that said at least one electromagnetic source irradiates at least a portion of said glass object at said at least two wavelengths; measuring a transmitted intensity level of said electromagnetic energy, at said at least two wavelengths, through said glass object using said at least one electromagnetic detector at said predefined distance; generating at least one attenuation ratio from said at least two measured incident intensity levels and said at least two measured transmitted intensity levels at said at least two wavelengths using a computer-based platform operationally connected to said at least one electromagnetic detector; and determining if said glass object has an acceptable hardness characteristic parameter based on said at least one attenuation ratio.
