摘要

Abstract: The presented work is a versatile approach to time-dependent numerical modeling of active optical instruments. Based on a hybrid geometrical- and physical optics propagation code an optical modeling tool (OMT) has been developed. Mainly targeting at the simulation of astronomical telescopes it allows building linear and non-linear optical models for integration into dynamic end-to-end simulation environments with models for mechanical structure, control systems and various disturbances. The light propagation through an instrument is modeled by a sequence of polarization ray tracing and diffraction propagations. A radiometry algorithm based on a triangle grid interconnecting the rays computes the calibrated power flux. Recently the OMT has been implemented as an optical kernel within the End-to-End Model for the Very Large Telescope Interferometer (VLTI) developed at the European Southern Observatory. There it performs the dynamic computation of the electric field in the exit pupils of the VLTI including polarization, radiometry and diffraction effects. !12
