Using two-point LDA systems, estimates of the integral length scales of turbulent flowfields can be performed by forming the cross-correlation function of the two velocity records for various measurement volume separations. Several estimators for the cross-correlation function are reviewed and their bias and variance are examined as a function of particle density and of chosen processing parameters. The investigations were performed using numerical simulations.
