Study Notes
Infrared Thermography Overview
- Infrared thermography operates within the electromagnetic spectrum range of approximately 0.7 to 14 micrometers.
- This technique primarily utilizes infrared radiation, which is not visible to the naked eye but can be detected as heat.
Capturing Anomalies
- Infrared thermography captures temperature variations on surfaces to identify anomalies, indicating potential issues such as heat loss, electrical faults, or moisture intrusion.
Non-Destructive Control
- Non-destructive control refers to methods that assess materials or systems without causing damage; infrared thermography allows for inspection while preserving the integrity of the objects being analyzed.
Fundamental Principles
- The basis of infrared thermography lies in the detection of infrared radiation emitted by objects, which correlates to their temperature. Higher temperatures emit more radiation, facilitating the identification of thermal anomalies.
