航空工程复杂光学系统的计算机辅助设计

针对不共轴的或含有复杂形面的光学系统,探讨其在计算机上的最优化设计。讨论了新型优化质量指标的建立、对不收敛状态的识别查处、边界约束及非线性处理等问题。

CAD OF THE COMPLICATED OPTICAL SYSTEMS IN AERONAUTICAL ENGINEERING

Optical automatic design of cornplicated optical systems and non-coaxial optical systems in aeronautical engineering is discussed, the rnain theoretical and technical problems in CAD of these optical systems are studied.The main problems include the application of Chebyshev numer-ical integral theory to build a new type of quality function in automatic optimization, coordination of the new type of quality index with traditional spot diagram in order to resolve the contradiction between the calculation quantity and optimization quality of the optical system,automatical recog-nition adn handling of slow convergent or divergent states,treatment of nonlinearity in iterations,and the way to extract the information of boundary quality of the system and eliminate the violations of the boundarv conditions.
