Wave optics and image formation in gravitational lensing [PDF]
Yasusada NambuWe discuss image formation in gravitational lensing systems using wave optics. Applying the Fresnel-Kirchhoff diffraction formula to waves scattered by a gravitational potential of a lens object, we demonstrate how images of source objects are obtained directly from wave functions without using a lens equation for gravitational lensing.View original: http://arxiv.org/abs/1207.6846
