title: Image processing for laser speckle velocimetry using the 2-D fast Fourier transform.
abstract: An algorithm is described for the fringe analysis in laser speckle velocimetry. Based on the 2-D fast Fourier transform, the method relies on inherent features in the fringe pattern to remove efficiently the influence of the diffraction halo. A windowing operation is performed to enhance the reliability and reduce the influence of various noise contributions.
