title: Accuracy of measuring systems using dynamic speckles.
abstract: Diffraction-limited accuracy is estimated for measuring systems exploiting dynamic speckles. Statistical properties of the signal in the systems with spatial filtering are used to evaluate the signal frequency with precision sufficient to achieve the diffraction-limited accuracy. The results of the analysis allow for designing an optimal measuring system in which components are matched with each other to provide the highest accuracy. Experiments carried out with a range sensor using spatially filtered dynamic speckles are in good agreement with theory.
