What Is Infrared Thermography?

Due to the existence of black body radiation, any object radiates electromagnetic waves to the outside according to the temperature. The part with a wavelength of 2.0 ~ 1000 microns is called thermal infrared. Thermal infrared imaging can reflect the temperature field on the surface of the object by imaging the thermal infrared sensitive CCD. Thermal infrared has a wide range of applications in the military, industrial, automotive assisted driving, and medical fields.

Principle

biological

Infrared thermal imaging is now being used in clinical research in major hospitals.

The principle of infrared thermal imaging is not mysterious. From the principle of physics,

The human body is a natural source of biological infrared radiation, which can continuously emit and absorb infrared radiation to the surroundings. The temperature distribution of the normal human body has certain stability and characteristics, and the temperature of each part of the body is different, forming different thermal fields. When a disease or function changes somewhere in the human body, the blood flow there will change accordingly, resulting in changes in the local temperature of the human body, manifested as high or low temperature. According to this principle, the infrared radiation of the human body is collected by a thermal imaging system and converted into digital signals to form a pseudo-color heat map. Using special analysis software, a professional physician analyzes the heat map to determine the location of the human lesion, the nature of the disease and The degree of the disease provides a reliable basis for clinical diagnosis.
