Abstract
A new untouchable measurement method, i.e. displacement sensing with laser interference is presented in this paper. This method is used for real-time and continuous measurement of displacement and vibration for engineering structures, and has the advantages of wide measurement adjusting range, high stability of interference fringes and low sensibility to environment. In this paper, the principle of the method is described, and the measuring results of typical structures are given. The prospects of the applications in measuring displacement and vibration for engineering structures are also discussed.
