Abstract
The invention disclosed herein generally relates to a device and methods to authenticate the composition of materials, including, but not limited to gold and silver coins and gold and silver bars. The invention stimulates the natural frequencies of the tested object and then compares them to a reference dataset to confirm its authenticity. It achieves this through use of a transducer that both vibrates the object and collects amplitude response, allowing for consistent and highly accurate analysis across a broad spectrum, including ultrasonic frequencies.
Claims15
A device for authenticating the composition of a substance by comparing it to a reference standard, comprising:
- (a) a transducer for vibrating the substance and for measuring its response;
- (b) peak analysis algorithms for determining the presence of a response;
- (c) a reference standard of the same substance for comparison.
A device for authenticating the composition of a substance by comparing it to a reference standard, comprising:
- (a) transducers for vibrating the substance and for measuring its response;
- (b) peak analysis algorithms for determining the presence of a response;
- (c) a reference standard of the same substance for comparison.
A device for authenticating the composition of a substance by comparing it to a reference standard, comprising:
- (a) transducers for vibrating the substance and for measuring its response, wherein specific frequencies associated with the natural frequency of the substance are excited and subsequently measured;
- (b) peak analysis algorithms for determining the presence of a response;
- (c) a reference standard of the same substance for comparison.
