摘　　要：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。There are several problems of the present laser pointing system of shipborne weapons, such as small imaging spot and its possibility deviating from the field of view under dynamic conditions. In order to overcome the disadvantages, a graded index optical waveguide was used to extend the imaging laser in one dimension perpendicular to the propagating direction. The laser beam was extended in only in one direction, keeping invariable in the other direction. Experiments on the modified system show that the point performance of the extended beam is good.
