摘要

光机系统的优化设计具有效率高、迭代周期短等特点,但对复杂光机系统的优化存在收敛难的问题。设计了一种基于拉丁超立方与径向基函数(RBF)神经网络结合的近似优化算法,并将其应用于带有曲率误差调整机构的拼接式望远镜主镜设计中。仿真结果表明,该算法优化后的主镜达到了设计指标,为解决复杂光机系统迭代时间长的问题提供了新思路。

Abstract

The optimization design of an optical-mechanical system has the characteristics of high efficiency and short iteration period, but the optimization of the complex optical-mechanical system has the problem of difficulty in convergence. An approximate optimization algorithm based on the combination of Latin hypercube and radial basis function (RBF) neural network is proposed in this work, and it is applied to the design of main mirror of spliced telescopes with curvature error adjustment mechanism. Simulation results show that the main mirror optimized by the algorithm has reached the design index, which provides a new idea for solving the problem of long iteration time for complex optical-mechanical system.
