Overview
1.1
Principle of Thermal Imaging and Advantages
Any object with temperature higher than the absolute zero (-273.15
°
F) will emit
infrared (IR) ray, even though it does not emit light. The IR ray is also called thermal
radiation. IR rays emitted by objects with different temperatures can be absorbed by the
detector to reflect temperature change and thus generate an electric effect. The electric
signal is amplified and processed to produce a thermal image that corresponds to the
thermal distribution of the object surface. This is the process of thermal imaging.
Adapt to any environment
Traditional cameras rely on natural or environmental light to shoot images, but this
IR thermal imaging camera relies on the IR energy radiated by an object itself to
form an image, not requiring any light. The IR thermal imaging camera is
applicable to any environment and not affected by light strength. It can detect and
identify any camouflage and concealed object both in daytime or nighttime,
implementing round-the-clock monitoring.
Monitor the temperature field with object energy distributed
The IR thermal imaging camera can show the temperature field of an object,
converting the invisible surface temperature distribution situation to a visible
thermal image that reflects the surface temperature distribution situation of the
object. By this monitoring, users can discover temperature anomaly in a timely
manner and take precautionary measures to avoid any risk that may be caused by
the anomaly, for example, a fire.
Boast cloud penetration capability
Visible light and near IR ray will be absorbed by the air, cloud and smoke, but they
are transparent to IR ray of the 3~5
μ
m Medium Wavelength Infrared (MWIR)
region and 8~14
μ
m Long Wavelength Infrared (LWIR) region. Traditional
cameras cannot shoot clear images under cloudy environment, but the IR thermal
imaging camera can penetrate the cloud and smoke to shoot clear images.
