摘要：
Adjustable real-time interval technique of digital shearing speckle interferometry is proposed and discussed in this paper and the corresponding computer software is developed. The applications of the technique to nondestructive testing (NDT) of leakage of pressured vessels and measurement of thermal deformations are also demonstrated, which show that the technique is valid. It makes it possible and convenient for long time and large area measurements and testing.
