  "abstract": "Gravitational lensing by rotating black holes is modelled, and the null geodesic equations in the strong field regime are integrated numerically. Observational signatures of the black hole spin parameter are identified by comparing image locations and shapes of extended sources at different a values. For the black hole at the centre of our Galaxy, angular resolutions of the order of hundreds of µas are needed to distinguish between the true source position and gravitationally lensed image position. Angular resolution below 1 µas is needed to determine the spin parameter of the Galactic black hole using gravitational lensing.",
