Rotating aperture method of speckle photography for analysing deformation of a dynamic heating object |
| |
| Abstract: | Rotating aperture method of speckle photography is applied to measure deformation of dynamic heating objects for the first time. The dynamic process can be recorded on a single speeklegram and can be resolved or reconstructed continuously by whole-field filtering. The quantitative analysis agrees well with results of other methods. |
