AI 中文摘要
我们提出一个两阶段优化框架，将经典光学设计策略形式化为可复现的计算工作流。起始点设计由近轴和三级像差模型构建，提供光学一致的初始构型。这些构型通过由精确光线追迹评估的物理接地残差评价函数进行细化，随后进行基于均方根（RMS）的图像细化。将该方法应用于多通道天文焦比缩减器，该框架提供了从基于像差的建模到数值优化的结构化过渡，同时保留了物理可解释的中间阶段。通过将经典光学设计原理嵌入开放计算流水线，该方法减少了对启发式初始条件的依赖，并提高了设计过程的可复现性和可解释性。
英文摘要
We present a two-stage optimization framework that formalizes classical optical design strategies within a reproducible computational workflow. Starting point designs are constructed from paraxial and third-order models, providing optically consistent initial configurations. These configurations are refined through a physically grounded residual merit function evaluated by exact ray tracing, followed by RMS-based image refinement. Applied to a multi-channel astronomical focal reducer, the methodology provides a structured transition from aberration-based modeling to numerical optimization while preserving physically interpretable intermediate stages. By embedding classical optical design principles into an open computational pipeline, the approach reduces reliance on heuristic initial conditions and improves the reproducibility and interpretability of the design process.
