In nature, everything with a temperature above absolute zero (-273.15°C) radiates infrared light every second of every day. Together with visible light, ultraviolet light, X-rays, gamma rays, cosmic rays and radio waves, it constitutes a complete and continuous electromagnetic spectrum. Its wavelength is between 0.78 μm and 1,000 μm, and it is a non-visible light with a wavelength longer than that of red light.
The physical nature of infrared radiation is thermal, and an infrared camera generates an image of heat rather than light; it measures infrared energy and converts the data into a corresponding temperature image. Infrared thermal imaging camera is the infrared thermal radiation into the corresponding electrical signals, and then after amplification and video processing, the formation of video images that can be observed by the naked eye. In layman's terms, it is the invisible infrared radiation into a visible thermal image, and can reflect the temperature distribution state of the target surface
The main role of the thermal imaging camera is temperature measurement and night vision, with safety, intuitive, try to measure the temperature of the characteristics of the equipment equipment (thermal imaging camera) has a wide range of uses, can be used for electric power detection, scientific research and temperature measurement, medical care, iron and steel metallurgy, HVAC testing and other scenarios.
