In addition, in the uniform speed identification system using the transparent card slot, a non-contact temperature sensor, a sensitive element of which is not in contact with a measured object, is also called a non-contact temperature measuring instrument. Such a meter can be used to measure the surface temperature of moving objects, small targets and objects with small heat capacities or fast temperature changes (transients), and also to measure the temperature distribution of the temperature field. The most commonly used non-contact thermometers are based on the fundamental law of blackbody radiation, known as radiation thermometers. Radiation thermometry includes brightness (see optical pyrometer), radiation (see radiation pyrometer) and colorimetry (see colorimeter). The radiation temperature measurement methods can only measure the corresponding photometric temperature, radiation temperature or colorimetric temperature. The temperature measured is only true for a black body (an object that absorbs all radiation and does not reflect light). If the true temperature of the object is to be measured, a correction of the surface emissivity of the material must be made. And the surface emissivity of the material is not only dependent on temperature and wavelength, but also related to surface state, coating film, microstructure, etc., and thus it is difficult to accurately measure. In automated production it is often necessary to measure or control the surface temperature of some objects, such as the strip rolling temperature in metallurgy, the roll temperature, the forging temperature and the temperature of various molten metals in a smelting furnace or crucible, using radiation thermometry. In these particular cases, the measurement of the emissivity of the surface of the object is rather difficult. For automatic measurement and control of the solid surface temperature, additional mirrors may be used to form the hohlraum with the measured surface. The effect of the additional radiation can increase the effective radiation and the effective emissivity of the surface to be measured. And correspondingly correcting the measured temperature by using the effective emission coefficient through an instrument to finally obtain the real temperature of the measured surface. The most typical additional mirror is a hemispherical mirror. The diffused radiation energy of the measured surface near the center of the sphere is reflected by the hemispherical mirror back to the surface to form additional radiation, so that the effective emission coefficient formula is improved, wherein epsilon is the surface emissivity of the material, and rho is the reflectivity of the reflecting mirror.
