Xuchang Infrared Heating Technology and Its Applications

The Research on Xuchang Infrared Heating Technology and Its Applications Infrared radiation sources are objects that emit infrared radiation. Physics research informs us that in nature, any object with a temperature above absolute zero (0°K or -273°C) emits various wavelengths of infrared radiation. The higher the temperature of an object, the greater the intensity of its infrared radiation. By utilizing the differences in radiation characteristics of various targets and backgrounds, infrared technology can be employed to detect, track, and identify targets during both day and night, thereby obtaining target information. Applications of Infrared Technology in Daily Life Nowadays, infrared technology is continuously being integrated into our daily lives, playing a role in many situations. Automatic doors at airports, hotels, shopping malls, and other places open and close automatically as people enter and exit. On one side of the automatic door, there is an infrared light source that emits infrared radiation onto a phototube on the other side. Infrared radiation is imperceptible to the human body. When a person approaches the doorway, their body blocks the infrared radiation, preventing the phototube from receiving it. According to pre-programmed instructions, this triggers a switch, opening the door. Once the person enters, the phototube can once again receive the infrared radiation, restoring the original circuit, and the door automatically closes. Therefore, this type of phototube is known as the "electric eye" and is widely used in various automatic control devices.
