Abstract

Mathematical and computer modeling of an optical system with a segmented mirror are designed and applied to a telescopic system. The unique feature of this presentation is to establish a center of the segments (sub-aperture arrangement) mathematically that provides six degrees of freedom (i.e. dx, dy, dz, α, β, γ) to each sub-aperture in order to input the mounting errors. To do so, a Visual Basic routine based on CODE V's COM interface is written that makes it possible to model all types of segmentation modes in a fast and convenient way. Segment results are discussed and the image quality of the design based on these results is evaluated in this paper.
