All objects in nature with temperatures above absolute zero (-273.15°C) can radiate infrared energy, and the physical nature of infrared radiation is thermal radiation, which is also an electromagnetic wave.
The infrared thermal imaging camera converts infrared thermal radiation into a corresponding electrical signal, which is then amplified and video processed to form a video image that can be observed by the naked eye. In layman's terms, this means that the invisible infrared radiation is turned into a visible thermal image, and can reflect the temperature distribution state of the target surface.
This thermal image corresponds to the heat distribution field on the surface of the object. Different colors on the thermal image represent different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the target under test can be visualized, and the heat generation of the target can be studied so that the next step can be judged.
Compared with devices that utilize visible light, because infrared thermal imaging technology is a passive, non-contact detection and identification of the target, it is therefore well concealed and not easily detected, thus making the operator of the infrared thermal imager safer and more effective.
In addition, in the complete absence of light at night, or in the rain, snow and other smoke clouds and other harsh environments, to be able to clearly observe the target to be monitored. It is due to this feature that thermal imaging cameras can really do 24h all-weather monitoring.
With the continuous development of infrared thermal imaging technology and the cost of exploration, thermal imaging cameras began to be widely used in electric power, industry, agriculture, security, medical, firefighting, archaeology, transportation, geology and other civilian fields.
Many thermal imaging camera brands have a wealth of applications. For example, High-Tech Intelligent Sensing can provide infrared thermal imaging products and solutions with strong performance, good experience and excellent service for various industries, and has abundant application cases and user feedback in dozens of key industries.
