摘要
基于实际激光除冰过程对光斑尺寸与作用距离的需求, 根据激光器功率与抗激光损伤阈值的工艺参数, 确定激光除冰光学系统的纵向长度与横向尺寸, 据此设计了作用距离为100~500 m且光斑尺寸为200~600 mm可调的抗高功率损伤光学系统.针对激光作用距离、光斑尺寸与调焦距离的关系曲线进行了理论计算与模拟仿真, 仿真结果表明系统可实现所需的作用距离与光斑, 并经实际样机实验得以验证.
Abstract
Based on the actual requirements of laser deicing process on the spot size and the action distance, the length and transverse dimensions of the laser deicing optical system are calculated according to the process parameters of laser power and anti-laser damage threshold. Then, the adjustable focusing optical system of high power damage with 100~500 m action distance and 200~600 mm spot size is designed. Focusing on the relationship between action distance, spot size and adjustment focusing distance, the theoretical calculation and simulation are carried out. The simulation results show that this system can achieve the desired adjustable distance and spot, which is verified by actual prototype experiments.
