Phase Map Retrieve with Temporal Speckle Pattern Interferometry
When the speckle interferometry or the electronic speckle pattern interferometry (ESPI) is applied to measure the continuous movement or the deformation of an object, the temporal speckle patterns can be recorded. By analyzing these time-sequence speckle patterns, the continual deformation of the tested object is obtained. A new method is proposed for measuring the object deformation based on analysis the fluctuation of time sequence speckle patterns. Two experiments have been conducted to demonstrate the performance of the method.
