Technical Problem
[0006]鉴于以上现有技术的缺点，本发明提供一种用于激光冲击强化的激光柔性传输装置，以改善现有的激光冲击强化光路搭建困难，导致激光冲击强化范围受限、激光可达性差等技术问题
Benefits of technology
现有的激光冲击强化技术采用的方案为硬光路传输、导光，对于部分复杂的内部，如飞机的内部结构而言，硬光路搭建困难、运动范围受限，导致无法对内部隐蔽部位进行处理。本申请通过在硬光路的末端设置阵列光镜，阵列光镜用于降低脉冲激光功率密度，降低功率密度后的脉冲激光通过传输光纤进行传输，传输光纤具有很好的柔性、操作性、可达性等，便于对内部结构进行激光冲击强化，从而提高结构修复的便利性。传输光纤的末端连接有反向阵列光镜，反向阵列光镜用于还原传输光纤传输的激光的功率密度，从而保证激光冲击强化时的能量和功率密度。
