The optical shape will be influenced seriously by these factors. But the impacts will not be shown in linear analysis results  because as the simplification  these factors have been ignored. The nonlinear analysis method for predicting optical surface deformations resulted from assembly process is discussed in detail. Take a typical mirror support structure for example  the nonlinear analysis model was established. Comparing the calculation results with the optical shape test  it is illustrated that nonlinear analysis is more accurate and closer to the test result. And according to the simulation result  the bowl-shaped depression which was discovered in the test can also be explained reasonably. 2010 Copyright SPIE - The International Society for Optical Engineering.
