Abstract

A model of the dynamics of the Large Earth-based Solar Telescope (LEST) is briefly described. The model includes the various subsystems of the telescope, with emphasis on its live optics system, which is used to correct for various kinds of disturbances, in particular the atmospheric turbulence, in real time. The disturbances are also modelled, and used as input to the telescope model. The modelling of the atmospheric turbulence is described, and results from simulations show the influence of the atmosphere during different seeing conditions.
