基于二维高速振镜的船载动态目标激光快速捕获研究

Fast Laser Capture of Dynamic Target Using Two-Dimensional High Speed Galvanometer

针对船艇在海上始终处于随机的晃动状态,为实现船载激光通信对目标的快速捕获,通过伺服系统的捕获设计和捕获时间计算,提出基于二维高速振镜的快速捕获方案,并通过模拟实验验证方案的可行性。实验证明,设计的船载快速捕获系统能在1 s内快速捕获到动态目标,虽然捕获所需的时间比理论计算所需的时间要长,但仍可以快速捕获到动态目标。

To quickly capture dynamic targets with shipboard laser communication means, the paper takes into consideration stochastic shaking state of a watercraft at sea and through capture design and capture time calculation of a servo system,develops a fast acquisition plan. The experiment with a simulated plan shows that the fast acquisition system can rapidly capture moving objects in one second, which is a bit longer than theoretical calculation result.
