By combining with dynamic isochromate pattern, the elastic modulus, Poisson's ratio and dynamic material fringevalue of the material measured can be obtained by the method.
如果和动光弹等色线结合，可以同时获得被测材料的弹性模量、泊松比、材料条纹值参数。

The article will contrapose maximum value method based on detecting image grey grad, and take example of SOBEL operator to realize digital image fringe picking up based on hardware (CPLD).
