Objects with a temperature above 0K will radiate infrared rays due to their own molecular motion. After the power signal radiated by the object is converted into an electrical signal by the infrared detector, the output signal of the imaging device can completely simulate the spatial distribution of the surface temperature of the scanned object in one-to-one correspondence, and then be processed by the electronic system and transmitted to the display screen. Obtain a thermal image corresponding to the thermal distribution on the surface of the object. Using this method, the imaging and temperature measurement of the long-distance thermal state image of the target can be realized, and the analysis and judgment can be carried out.

 

Infrared imaging technology is an imaging method that displays the temperature change on the surface of an object by measuring the change of infrared radiation brightness. Compared with the contact temperature measurement method and the infrared detection method, it has the advantages of faster response time, non-contact, safe use and long service life.
