| Abstract: | The clarity of whole-field pattern in objective speckle method is influenced by the following factors: preparation of the specimen surface; type of holographic plate adopted; processing of developing and fixation; how to attach holographic plate to specimen: and the procedure of taking whole-field fringe pictures, proper treatments and preparation are introduced. The experimental results show clear patterns and are well agreed with the value by finite element calculation. |

| Keywords: | objective speckle whole field fringes of speckle. |
