OPTICAL MODELING FOR DYNAMICS AND CONTROL ANALYSIS

This paper presents a coordinate-free ray-trace analysis of optical beam trains consisting of mirrors, lenses, and reference surfaces. The analysis leads to optical models that can be directly integrated with standard structure and control models for integrated instrument design, analysis, and simulation. This capability is required for a coming generation of space-borne optical instruments that use controlled optical elements supported by flexible structures. New results include analytic formulas for optical sensitivities as functions of structural and control geometric parameters. An example problem calculates a linear (small-motion) optical model, derives optical gains for small- and large-angle controlled mirrors, and shows the propagation of a wave front.
