Abstract: This article introduced the experiment theorem and device of calculating the material linear expansive coefficient with the holographic interferometry.We obtained the first stept result and adopt forward the further improvement of the experiment and the method to decrease experiment error.The experiment is a new application of holographic interferometry to this field.

Key words: double exposure, linear expansive coefficient, small displacement, columnar electric heater, holographic interferometry, double exposure, linear expansive coefficient, small displacement, columnar electric heater
