Do you know what an infrared thermometer is?

All objects whose temperature is higher than absolute zero are constantly emitting infrared radiation energy into the surrounding space. The size of the infrared radiation energy of an object and its distribution according to wavelength-have a very close relationship with its surface temperature. Therefore, by measuring the infrared energy radiated by the object itself, its surface temperature can be accurately determined, which is the objective basis on which infrared radiation temperature measurement is based.

Blackbody radiation law: A blackbody is an idealized radiator, which absorbs all wavelengths of radiant energy, without energy reflection and transmission, and its surface has an emissivity of 1. It should be pointed out that there is no real black body in nature, but in order to clarify and obtain the distribution of infrared radiation, an appropriate model must be selected in theoretical research. This is the quantized oscillator model of body cavity radiation proposed by Planck, which is derived Planck’s law of black body radiation, that is, the spectral radiance of a black body expressed in wavelength, is the starting point of all infrared radiation theories, so it is called the law of black body radiation.

Infrared thermometer is to use infrared detector, optical imaging objective lens and photo-mechanical scanning system to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector. Between the optical system and the infrared detector, there is a light The machine scanning mechanism scans the infrared thermal image of the measured object and focuses it on the unit or spectroscopic detector. The detector converts the infrared radiation energy into an electrical signal, which is amplified, converted, or standard video signal is passed through the TV screen or monitored The monitor displays the infrared thermal image.

The thermal image of the infrared thermometer corresponds to the thermal distribution field on the surface of the object; in essence, it is the thermal image distribution of the infrared radiation of each part of the measured target object. Because the signal is very weak, compared with the visible light image, it lacks layering and three-dimensionality. Therefore, in order to more effectively determine the infrared heat distribution field of the measured target in the actual action process, some auxiliary measures are often used to increase the practical functions of the instrument, such as image brightness and contrast control, real standard correction, false color depiction, etc. Technology
