| Abstract: | The inner grating moiré method is suitable for 3-dimension deformation measurement,especially in measuring mechanical distributions of contact problem and inner deformation.By introducing the wavelet transformation,the digital moiré patterns are generated conveniently.The principle of simulating moiré patters is explained in detail.An application is studied,and the results show that the method is feasible. |
