Description
I will present a covariant and observer-independent approach to geometric optics in GR. I will discuss how one can calculate the parallax, the image distortion and magnification and the position drift, including all GR effects, of a distant source using bilocal optical operators. The formalism can be applied to any metric and has potentially important applications to cosmology and relativistic astrophysics.
