The traditional deformation measurement have many limitations, According to actual measurement need, it is requested not only comprehensive, flexible, high-precision, but also can describe the various points displacement within the measurement scope at any time, get the most comprehensive data. In this paper, used speckle methods to carry on deformation accurate and comprehensive measuring. First, compared with traditional methods, showed its many advantages, including: non-contact, high precision, operation simple and flexibility, etc. Then specified the main basic theory of the speckle method, established relevant mathematical models, developed the appropriate measurement and analysis software XJTUDIC, and used the software with the appropriate hardware equipment to test a specific tensile deformation process, and compared the results with using traditional extensometer measurement methods, through calculation got the error is within ± 0.2%. This fully validated the method and corresponding software and hardware were reliable, feasible and excellent.
