Due to fluid processing, photoelectric effect and thermoelectric measurement and subtraction between the sample and the detector, the optoelectronic technology used in the standard distribution systematically underestimates the thermal diffusivity of the solid sample. In order to solve the negative effects in the process of treating fluids in this study, a completely new method will be proposed. It depends on the application of the transparent thermoelectric sensor as well as the transparent coupling of the fluid, as well as the self-standardization process. In this sense, it is easy to measure examples of accurate opacity and solidity of thermal diffusivity, as well as the light absorption coefficient of translucent solid samples.
