The work presents the comparative method of determining linear coefficient of thermal expansion for stiff materials in the small range of temperatures (20÷40 °C). The phenomenon of optical interference was used for the continuous measurements and relative changes of thermal extensions. The applied sodium light permitted the measurement of expansion as a function of changes of temperature with accuracy 0,3 [µm]. The described method was applied for composite hybride materials as well as for hard tissues of animal teeth.
