Abstract

The paper presents a new optical modeling tool developed for solving the optical sensitivities with respect to air perturbation. The tool is a Matlab based software package allowing the user to configure the model, select analysis options and process the results. When assessing the impact of disturbances on high-performance systems, it is critical that the disturbance models can be fairly representative of the actual disturbances. Partitioning the clam air by many planes, we can view the air as an array of lens of different index of refraction and the air perturbation as the planes jitter. The overall model architecture is presented in detail. The overall framework is applied to an integrated model of telescope to demonstrate its practical use. The simulation results show the air turbulence near two mirrors affect the performance of system mostly, with the air turbulence near primary mirror being dominant.
