Gravitational lensing by gravitational waves

G.S. Bisnovatyi-Kogan1 and O. Yu. Tsupko2


Gravitational lensing by a gravitational wave is considered. We notice that, although the final and initial directions of photons coincide, there occur5s a displacement between the final and initial trajectories. This displacement is calculated analytically for a plane gravitational wave pulse. Observational estimates are discussed.
