| Abstract: | In this paper, the heat transfer equation for photothermal radiometry is built.The new heat flux conservation boundary conditions are established. The temperature distribution from absorbing light is the solution of the equation. Treatment of thermally thin layer and thermally thick lager from photothermal signal is discussed .Theoretical investigation of the new metrological technique-photothermal-radiometry has unique significance. |
