Abstract
A method, apparatus, and computer usable program code for non-destructive detection of corrosion using quantum dots. In one embodiment, a surface of an area on a commodity associated with a set of quantum dots is tested. A pattern of wavelengths emitted by the set of quantum dots associated with the surface of the commodity is detected to form a quantum dot pattern. The quantum dot pattern is analyzed to determine whether corrosion has occurred in the area on the surface of the commodity.

A method for non-destructive detection of corrosion using quantum dots, the method comprising:
- testing, by a number of quantum dot detectors operably coupled to a data processing system, a surface on a commodity associated with a set of quantum dots to form a test area;
- detecting, by a processor of the data processing system, a pattern of wavelengths emitted by the set of quantum dots associated with the test area of the commodity to form a quantum dot pattern, wherein the set of quantum dots emits different colored lights in different sets of patterns of wavelengths;
- identifying, by the processor, an intensity of wavelengths in the pattern of wavelengths emitted by the set of quantum dots;
- analyzing, by the processor, the quantum dot pattern to determine whether corrosion has occurred in the test area, wherein the set of quantum dots emit an expected pattern in the absence of corrosion, and wherein the corrosion changes the expected pattern;
- and
- determining, by the processor, an amount and a severity of corrosion in the test area of the commodity based on the quantum dot pattern and the intensity of the wavelengths.
A computer program product comprising:
- a non-transitory computer readable medium containing computer usable program code for non-destructive detection of corrosion using quantum dots, said computer program product comprising:
- computer usable program code for detecting a pattern of wavelengths emitted by a set of quantum dots associated with the surface of the commodity to form a quantum dot pattern in response to a test of a surface of a commodity associated with a set of quantum dots to form a test area, wherein the set of quantum dots emits different colored lights in different sets of patterns of wavelengths;
- computer usable program code for identifying an intensity of wavelengths in the pattern of wavelengths emitted by the set of quantum dots;
- computer usable program code for analyzing the quantum dot pattern to determine whether corrosion has occurred in the test area of the commodity, wherein the set of quantum dots emit an expected pattern in the absence of corrosion, and wherein the corrosion changes the expected pattern;
- and
- computer usable program code for determining an amount and a severity of corrosion in the test area of the commodity based on the quantum dot pattern and the intensity of the wavelengths.
A system for non-destructive detection of corrosion using quantum dots, the system comprising:

- identifies an intensity of wavelengths in the pattern of wavelengths emitted by the set of quantum dots;
- analyzes the quantum dot pattern to determine whether corrosion has occurred in the test area of the commodity, wherein the set of quantum dots emit an expected pattern in the absence of corrosion, and wherein the corrosion changes the expected pattern;
- and determines an amount and a severity of corrosion in the test area of the commodity based on the quantum dot pattern and the intensity of the wavelengths.
