Product Overview
1.1 Thermal Imaging Principles and Advantages
For any object, as long as its temperature is above the absolute zero (-273.15
°
C),
although the object does not give out light, it can radiate infrared. The infrared is also
known as thermal radiation. A temperature change occurs when the infrared radiated by
objects at different temperatures is absorbed by the infrared thermal detector, and
thereby generating an electrical effect. An electrical signal is amplified and processed
to obtain a thermal image corresponding to the distribution of heat on the surface of the
object, that is, infrared thermal imaging.
Applicable to any light environment
Traditional cameras rely on the natural or ambient light for imaging. However, the
infrared thermal imaging camera can clearly image the object with the infrared heat
radiation of the object without relying on any light. The infrared thermal camera is
applicable to any light environment and is free from glare impact. It can clearly
detect and find the target as well as identify the camouflaged and hidden target in
both day and night. Therefore, it achieves real 24-hour surveillance.
Monitoring the temperature field of the target heat distribution
The infrared thermal camera can display the temperature field of the object and
change the surface temperature distribution of the object that cannot be directly
seen by human eyes to the thermal image representing the surface temperature
distribution of the object. By monitoring the temperature field, you can
immediately identify the temperature abnormality, thereby preventing potential
risks caused by the temperature, such as fire.
Providing the cloud penetration capability
Atmosphere, dust, and clouds can absorb visible light and near infrared, but are
clear to the thermal infrared for 3 to 5 microns (medium wave infrared region) and
8 to 14 micron (long wave infrared). Therefore, it is difficult for the conventional
cameras to capture clear images under dense clouds, while the thermal imaging
camera is able to effectively penetrate the atmosphere and clouds to capture clear
images.
