Abstract: | We show that gravitational light deflection is truly equivalent to the optical effect of a prism and a thin diverging lens when the massive deflector has cylindrical symmetry. We then investigate the possibility of cosmological measurements analogous to those proposed by Refsdal in the spherically-symmetric case.This work was partially supported by FINEP, CNPq, and CAPES. |
