Abstract

A stochastic process of structural finite element simulation of a two mirror telescope has been combined with vector electromagnetic analysis of the thermally stressed structure to determine the influence of material properties on performance at terahertz frequencies. The output gives a reliable understanding of the correlation between properties of the materials used in the building of the telescope, on a component by component basis, and the aberrations of the optics under operating conditions. In this study the only stresses considered were thermo-elastic and the optics were simple, but the method is generally applicable to any optical system and can take account of both stress induced deformation and assembly tolerances.
