Principles of Infrared Thermal Imaging Technology

Any object, as long as its temperature is higher than the absolute temperature of zero degrees (-273.15 degrees), can radiate infrared, which is also called thermal radiation. The infrared rays radiated by objects at different temperatures are absorbed by infrared thermal detectors to produce temperature changes, thereby generating electrical effects. The electrical signals are amplified and processed to obtain a thermal image corresponding to the heat distribution on the surface of the object, which is called "infrared thermal imaging."

The following are the benefits of infrared thermal imaging technology:

1 Adapt to any lighting situation

Traditional cameras rely on natural or environmental light to take pictures, while infrared thermal imaging cameras do not need any light and can clearly image by relying on the infrared heat radiated by the object itself. An infrared thermal imaging camera is suitable for any lighting environment and is not affected by strong light. It can clearly detect and find targets and identify camouflaged and concealed targets regardless of day or night. Therefore, it can truly realize day-and-night 24-hour monitoring.

2 With real cloud penetration ability,

Atmosphere, clouds, fog, and dust, for example, will absorb visible light and near-infrared rays, but for thermal infrared they are transparent, cause thermal infrared are transferred at 35 microns (medium-wave infrared region) and 8–14 microns (long-wave infrared region). The normal clear image is captured in the environment, but the infrared thermal imaging camera can effectively penetrate the atmosphere, cloud, fog, and other environments to capture clear images.

3 Temperature field monitoring of the target thermal energy distribution

The infrared thermal imager can display the temperature field of the object and convert the temperature distribution of the target surface that the human eye cannot directly see into a thermal image that can be seen by the human eye, representing the temperature distribution of the target surface. By monitoring the temperature field in real time we can find abnormal temperatures timely to prevent hidden dangers caused by abnormal temperatures, such as fire.

4 Exceptional temperature measurement and diagnostic abilities

An infrared thermal imaging camera is the only diagnostic technology that can instantly visualize and verify thermal information. The infrared thermal imager can accurately measure the surface temperature of the object by quantifying the infrared heat energy detected by non-contact and realize the abnormal diagnosis of the environment or the object by analyzing the thermal energy distribution and temperature of the scene. It can track the high temperature target in the scene or area and can send out an alarm when the temperature is higher than the set value.
