We discuss the resolution of pulsar magnetospheres using interstellar scint
illation. The two-dimensional spatial structure of pulsar emission zones ca
n be obtained from analysis of diffractive scintillations at low frequencie
s. Based on refractive and diffractive scintillation of pulsars we can also
reconstruct the distribution of turbulent plasma along the line of sight,
and using this analysis a new approach to pulsar distance estimation can be
made.
