Infrared thermal imaging technology in both civil and military applications, the beginning of the origin of the military, and gradually turned to civilian use. In the civilian generally called thermal imaging camera, mainly used in research and development or industrial testing and equipment maintenance, in the fire, night vision and security are also widely used. In layman's terms, a thermal imaging camera transforms the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured.
Infrared thermal imaging camera is a use of infrared thermal imaging technology, through the subject of infrared radiation detection, and signal processing, photoelectric conversion and other means, the subject of the temperature distribution of the image into a visual image of the equipment. The infrared thermal imaging camera will be the actual detected heat for accurate quantification, in the form of surface real-time imaging of the subject of the whole, and therefore can accurately identify is heating the suspected fault area. The operator uses the image color displayed on the screen and the hotspot tracking display function to make a preliminary judgment of the heat generation situation and the fault area, and at the same time rigorously analyzes it, thus demonstrating high efficiency and accuracy in identifying the problem.
