How is infrared energy related to problem detection?
Detectors in the infrared camera convert this incoming infrared energy from the infrared spectrum to the visual spectrum so we can see the infrared energy. These visual maps that co-relate image intensity or colour to the amount of infrared radiation received from that object. The amount of radiation received, along with other parameters, is used to calculate the actual surface temperature of the target object. The detectors are extremely sensitive to small temperature differences and, with a trained and experienced thermographer, inspections are accurate and very valuable.
