Abstract
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.
