Integrated Opto-Mechanical Analysis

Level: Advanced Length: 7 hours Format: In-Person Lecture Intended Audience: This course is intended for mechanical and optical engineers interested in learning about optomechanical analysis techniques and the use of modern software tools including finite element analysis and optical design software to design and analyze optical systems. Working knowledge or familiarity with finite element software and/or optical design software is recommended. Description: This course presents optomechanical analysis methods to optimize the performance of imaging systems subject to environmental influences. Emphasized is the application of finite element techniques to develop efficient and practical models for optical elements and support structures from early design concepts to final production models. Students will learn how to design, analyze, and predict performance of optical systems subject to the influence of gravity, pressure, stress, harmonic, random, transient, and thermal loading. The integration of optical element thermal and structural response quantities into optical design software including ZEMAX and CODEV is presented that allow optical performance metrics such as wavefront error to be computed as a function of the environment and mechanical design variables. Advanced techniques including the modeling of adaptive optics and design optimization are also discussed. Examples will be drawn from ground-based, airborne, and spaceborne optical systems. Learning Outcomes: This course will enable you to: - effectively model lightweight mirrors - develop FEA models of optical mounts, flexures, and metering structures - perform thermo-elastic analysis of optical systems - predict and represent the distortion of optical surfaces using Zernike polynomials - learn benefits of numerical optimization techniques for optical structures - design and analyze optical bonds including structural adhesives and RTV - perform analyses to predict optical surface correctability using adaptive optics - predict line-of-sight jitter in vibration environments - integrate thermal and structural results into optical models - predict the effects of stress birefringence on optical performance - develop models and perform analyses to predict assembly induced errors Instructor(s): Keith B.
