A Simulation Analysis of an Extension of One-Dimensional Speckle Correlation Method for Detection of General In-Plane Translation
Figure 3
Displacement of speckle pattern detected (a) in a selected narrow rectangular area of a detector, (b) in the whole area of the detector. Black ovals delimit shape of individual speckles. Speckle pattern is only shifted by , whereas . However, the speckle pattern displacement evaluated in the case (a) is .
