Abstract:
A computer optical installation for using the speckle dynamics in the study of stochastic microdisplacements was developed. The relationship between small displacements, deformations and rotations of the sample surface, and displacements and decorrelation of speckle pattern in a free space and in image plane was established. The installation allowed to record two-dimensional spatial-temporal patterns of speckle dynamics and visualize regular and stochastic microdisplacements on the sample surface in the process of its deformation.
