Abstract

Observational High Time Resolution Astrophysics differs from conventional astrophysics in regard to the detectors employed which have a time resolution less than that obtainable through CCD with a normal readout τ < a few minutes. This paper looks at the implications for HTRA from extremely large telescopes and specifically, as an exemplar its possible impact on pulsar astrophysics. We demonstrate, by using the derived point-spread-function from models of the Euro50 telescope, the possible effects active and adaptive mirrors have on observing rapidly varying astronomical objects.
