After having analyzed the different causes of macroscopic displacements of photo-carriers in LiNbO 3, the corresponding photoinduced changes of refractive index are computed for the short-circuited and open circuited crystal. It is shown in the second case that total or selective erasure can be performed, using a coherent substraction technique.Après avoir analysé les différentes causes de déplacements macroscopiques des porteurs de charges photoexcités dans LiNbO 3, on calcule les variations d'indice photoinduites correspondantes, pour les cas du cristal en circuit ouvert et en court-circuit. On montre dans le second cas qu'un effacement complet ou sélectif peut être obtenu par une méthode de soustraction cohérente
