摘要: 为了在机载振动环境下获得满足光学性能指标要求的偏振成像光谱仪镜头的最佳结构性能，建立了基于视轴抖动误差的优化模型，并在Isight集成优化环境下对该模型进行了求解。首先，阐述了视轴抖动误差影响光学系统性能的原理并根据光学系统模型和指标需求设计了镜头的初始结构；其次，推导了视轴抖动误差的计算方法并建立了基于视轴抖动误差的优化模型；最后，在Isight环境下，使用多岛遗传算法对优化模型进行了求解。结果表明：在满足镜头视轴抖动误差的要求下，镜筒质量降低了17.4%，镜头光学系统传函为0.4（77 lp/mm），满足设计指标要求。提出的优化方法引入镜头视轴抖动误差作为优化约束，拓展了光机结构优化的内涵，为同类结构的优化提供了新的思路。

Abstract: To achieve the best structure performance of the airborne polarization imaging spectrometer lens which meets the optical performance, the optimization model based on the line of sight jitter error was established and calculated in Isight environment. Firstly, the principle that the line of sight jitter error affected the performance of the optical system was elaborated and the initial structure layout was designed according to the optical model and performance. Secondly, the calculation method of the line of sight jitter error was deduced, based on which the optimization model was established. Finally, the optimization model was calculated by applying the Multi-island Genetic Algorithm in Isight environment. The computational result of the integrated optimization model shows that the mass of the lens barrel is reduced by 17.4%, which satisfying the constraint of the optimization model and the value of the optical transfer function is 0.4 (77 lp/mm), which meeting the requirement. The line of sight jitter error is applied during the procedure of the structure optimization presented, which expanded the connotation of optomechanic structure optimization and provided a new optimization idea for the same kind of structure.
