First, we check that geometrical optics is valid for the gw frequency range on which earthbased detectors are sensitive, and that this is also partially true for what concerns the future spacebased interferometer lisa. Other readers will always be interested in your opinion of the books youve read. Files are available under licenses specified on their description page. This effect is known as gravitational lensing, and the amount of bending is one of the predictions of albert einsteins general theory of relativity. Einsteins general theory of relativity demonstrates that a large mass can deform spacetime and bend the path of light. Academic publishers version preprint pdf sur le site du max planck institut.

A gravitational lens is a distribution of matter such as a cluster of galaxies between a distant light source and an observer, that is capable of bending the light from the source as the light travels towards the observer.
