Theoretical and experimental studies on the source image centroid displacement in the turbulent atmosphere under light flux fluctuations through a receiver telescope aperture are reviewed. The available data show inadequate account of the flux scintillation effect on the centroid displacement. The scintillations are found to increase the centroid variance as compared to the case where the light flux is constant.
