舰载武器系统激光对瞄方法研究

为了解决目前舰载武器激光对瞄系统存在对瞄成像光斑尺寸较小,以及在动态场景情况下该成像光斑极易偏离出观测视场等缺陷,采用渐变折射率平板波导对成像激光进行1维扩束,激光束在与传播方向垂直平面内的一个方向上进行很好的扩束,而在另一个方向上基本不影响原有光束的传输性能。对改进后的系统进行模拟实验。结果表明,扩束光线具备了较好的对瞄观测效果。

Research on optical waveguide point technique of shipborne weapon

There are several problems of the present laser point system of shipborne weapon. Such as the size of the imaging spot is small, and the spot will possibly deviate from the observation field of view on dynamic conditions. So this paper studies an improved system extending laser one-dimensionally using graded index optical waveguide. The laser beam is well extended in one direction, in the plane vertical to the direction of propagation, while do not change in the other direction. And the system is tested. The result shows that the point performance of the extended beam is good.
