Abstract
An apparatus for detecting cracks in a plurality of samples includes: a temperature source configured to heat or cool a section of the samples; one or more infrared cameras positioned near one or both sides of the samples and configured to receive infrared image data from the samples; a data acquisition and processing unit configured to generate a two-dimensional image out of the infrared image data to detect cracks in the samples; and a conveyor unit configured to transport the samples past the temperature source and the one or more infrared cameras.
Claims20
An apparatus, comprising:
- a temperature source configured to heat or cool a section of a plurality of samples;
- one or more infrared cameras positioned near one or both sides of the plurality of samples and configured to receive infrared image data from the plurality of samples;
- a data acquisition and processing unit configured to generate a two-dimensional image out of the infrared image data to detect cracks in the plurality of samples;
- and
- a conveyor unit configured to transport the plurality of samples past the temperature source and the one or more infrared cameras.
A method of detecting cracks in a plurality of samples, the method comprising:
- heating or cooling a section of the plurality of samples;
- collecting infrared image data from the plurality of samples;
- and
- transporting each sample of the plurality of samples before heating or cooling and after collecting the infrared image data.
A method of detecting cracks in a plurality of samples, the method comprising:
- heating or cooling the plurality of samples by placing the plurality of samples in an oven or chiller;
- removing the plurality of samples from the oven or chiller;
- collecting infrared image data from the plurality of samples;
- and
- generating a two-dimensional image out of the infrared image data to detect cracks in the plurality of samples.
