Refraction of pulsar radiation by electron density irregularities in the interstellar medium can sometimes produce multiple imaging of pulsars. Such events can be used as tools to resolve the emission regions in pulsar magnetospheres. Results from recent observations of a double imaging event for PSR B1133+16 are described. Significant fringe phase variations are seen across the pulse. The minimum value for the transverse separation of the emitting regions at the two edges of the pulse is inferred to be ≈ 5 × 105m. These results are compared with earlier values reported in literature and the implications are discussed.
