Paper Abstract

This paper presents the current status of development of a numerical toolbox for time-dependent simulation of optical single- and multi-aperture telescopes. ESO is developing the toolbox within the scope of the Very Large Telescope Interferometer (VLTI) project intending to use it during the commissioning phase of the interferometer. The toolbox components related to the different technical subsystems (structure, optics, control system, sensors) and disturbances are described. The main emphasis is put on a specifically developed optical modeling tool used for generating models of the optical signal flow that can be embedded in the dynamic simulation environment. A recently implemented algorithm allows to perform a pure physical optical (diffraction) analysis of the telescope optical system. Exemplary results of simulations on the VLTI illustrate the modeling approach.
