| Abstract: | The new method of measuring thermal expansion coefficient of solid state materlals isintroduced in this paper. A optical fiber displacement sensor has been used in our experiment tomeasure the thermal expansion coefficient of the copper metal bar. The differential method and linearregression method have been used to treat with the experimental data, respectively. Finally, themeasuring result is compared with the data given by reference4]. |
