In this article, we continue A. Labeyrie's work concerning the detection of Gravitational Waves through the deformations of optical wavefronts. We give the analytical expressions of the wavefront distortions. Special attention is paid to the discussion of this approach with respect to other works. The wavefront distortions are expected to cause a scintillation effect for a distant observer. The observability of this effect is discussed in the cases of binary stars and millisecond pulsars. It seems unobservable for a single monochromatic source of gravitational waves.
