Infinite Element Model for the Reconstruction of Two-Dimensional Shearing Wavefront |
| |
| Abstract: | Infinite element method for analysis of two—dimensinal shearing wavefront is presented and the infinite element mod el for the wavefront reconstruction is established. The results of the computer simulation demonstrate the high accuarcy of this method. Since the wavefront should satisfy all the 2-D shearing equations according to the finite element theory, the noise from the differences call be averaged. Thus the method is insensitive to measurement noise, suitable for teal testing. |
