| Abstract: | his paper has expounded the princile of measuring displacement by the method of laser speckles and derived the quantitative mathematical equation using Fourier's translation. It has also given the complete experiment process and measuring results of temperature coefficient of copper. Temperature field distribution of copper along the length has been obtained by measuring displacement. This means of measurement issimple and convenient and its sensitivity is high. |
