在科学和工业中，光束整形光学的对准通常是一个人工过程。许多利用光束整形光学系统的工业应用需要更具可扩展性的生产解决方案，因此已经投入了有关光学装配自动化的研究。在之前的工作中，作者和其他研究人员已经证明了自动对准光束整形光学器件（如准直透镜或均匀光学器件）的可行性。然而，规划工作以及来自自动化和控制领域的额外知识对于这种校准过程是巨大的。本文提出了一种规划光束整形光学系统主动对准过程的新方法，其重点是最小化主动对准的规划工作量。该方法利用光学模拟和计算机科学中的遗传规划范式，从模拟数据基础中自动提取特征，这些特征与单个对齐自由度具有高相关系数。该策略能够找到可由自动化装配系统执行的主动对准策略。本文提供了一种工具，使该算法可用于最终用户，并讨论了规划快速轴准直器的知名装配的主动对准的结果。本文最后展望了可转移到其他用例的前景，例如应用程序特定的强度分布，这将从减少的规划工作中受益。
In science and industry, the alignment of beam-shaping optics is usually a manual procedure. Many industrial applications utilizing beam-shaping optical systems require more scalable production solutions and therefore effort has been invested in research regarding the automation of optics assembly. In previous works, the authors and other researchers have proven the feasibility of automated alignment of beam-shaping optics such as collimation lenses or homogenization optics. Nevertheless, the planning efforts as well as additional knowledge from the fields of automation and control required for such alignment processes are immense. This paper presents a novel approach of planning active alignment processes of beam-shaping optics with the focus of minimizing the planning efforts for active alignment. The approach utilizes optical simulation and the genetic programming paradigm from computer science for automatically extracting features from a simulated data basis with a high correlation coefficient regarding the individual degrees of freedom of alignment. The strategy is capable of finding active alignment strategies that can be executed by an automated assembly system. The paper presents a tool making the algorithm available to end-users and it discusses the results of planning the active alignment of the well-known assembly of a fast-axis collimator. The paper concludes with an outlook on the transferability to other use cases such as application specific intensity distributions which will benefit from reduced planning efforts.
