Integrated Optomechanical Analysis
SPIE Press, 2002 - Technology & Engineering - 231 pages
The emphasis here is to present optomechanical modelling techniques to effectively design and analyse high-performance optical systems. The first goal is to discuss thermal and structural modelling methods using finite element analysis to predict the integrity and performance of optical elements and optical support structures. The second goal addresses the process of integrating thermal and structural responses into optical design software packages. Such integrated techniques allow the numerical simulation of optical system performance while including the multidisciplinary aspects of the design process. This leads to shorter design cycles, optimised designs, and models that accurately predict hardware behaviour.
