Paper Abstract

A method to predict performance of adaptive optical systems subject to mechanical perturbations is presented. Integrated modeling techniques coupling finite element analysis and optical design software are discussed that enable mechanical design trades of an adaptive mirror assembly based on correctability of the optical system wavefront error. This method is based on the linearity of wavefront error consistent with that caused by mechanical disturbances during operation. Optical surface sensitivities are computed based on rigid-body and higher-order surface deformations that relate mechanical surface errors to optical system wavefront error. The sensitivities are then used to determine the best-fit set of actuators to minimize the wavefront error in the optical system due to finite element derived mechanical disturbances. An example is demonstrated for a Cassegrain telescope with an active primary mirror.
