4. This technical scheme has all been injectd again simultaneously to the focus of fresnel lens, the distance between temperature sensor and the fresnel lens, the distance of fresnel lens and shell temperature measurement mouth for can carry out temperature compensation to remote temperature measurement through linear formula, increase the accuracy of non-contact infrared thermometer when remote temperature measurement.
