Thermal infrared imager is that a use optoelectronic device detects and measures radiation and builds between radiation and surface temperature
The vertical science connected each other.Radiation refers to generation when radiation energy (electromagnetic wave) is moved in the case of not having direct conductive medium
Heat moves.The operation principle of modern thermal infrared imager is to use optoelectronic device to detect and measure radiation, and at radiation and table
Set up between surface temperature and connect each other.All objects higher than absolute zero (-273 DEG C) all can send infra-red radiation.Infra-red heat
The infrared energy distribution pattern utilizing Infrared Detectors and optical imagery object lens to accept measured target as instrument reflects infrared
On the light-sensitive element of detector, thus obtaining Infrared Thermogram, this thermography is corresponding with the heat distribution field of body surface.Logical
Say that thermal infrared imager is exactly that the invisible infrared energy sent by object is changed into visible heat picture popularly.Above heat picture
Different colours represent the different temperatures of testee.By checking heat picture, it can be observed that the bulk temperature of measured target
Distribution situation, the heat condition of goal in research, thus carry out the judgement of further work.
The mode that the present invention uses visible images to be combined with thermal infrared images judges risk of forest fire, can significantly reduce forest
The misclassification rate of fire, improves the operational efficiency of system.
