3 Terms and Definitions

Terms and definitions GB/T 12604.9 defined apply to this document. 4. Summary 4.1 detection principle The basic principle of infrared thermal imaging detection method shown in Figure 1. Objects above absolute zero will produce thermal radiation, the radiation intensity and physical Material type, topography, temperature and other characteristics related. Infrared thermography is the use of radiation characteristics of an object to measure the temperature of the surface field. The basic method is by measuring body heat transfer, such as the mechanical parts of the insufficient lubrication, electrical equipment and so poor contact Body temperature changes caused by abnormal; infrared detectors could be the change, and by image processing techniques to convert it to visible light of FIG. Like on the display shows the temperature and the temperature of the object at each point difference in grayscale or pseudo-color form; analyze and process the images, access Status information of the measured object. Different visible light imaging, infrared imaging is the use of the target with the surroundings due to the difference between the temperature and emissivity of the resulting Thermal contrast is different, and the infrared radiation energy density distribution is displayed, a "thermal image", thus bringing the people's visual range from visible Extended to infrared light. ......
