摘要
阐述了原有的光纤时间延迟编码激光告警系统中使用的方位角判别方法,并分析了其不能够从根本上提高角分辨率的关键原因,提出采用一种通过改进光纤前端透镜耦合的方式来大幅度提高系统角分辨率的新方法,结果表明该新激光探测头的设计方式可使系统的角分辨率提高一个数量级.
This paper expatiates on the customary method to obtain the azimuth angle for laser beam in optical fiber time delay laser warning systems, and analyzes the key reasons why this method can not improve the sensitivity of angular resolution, and through theoretically analysis, puts forward a novel technology im- proving the coupling fashion of the optical fiber front with lens which can greatly advance the angular resolution. The result shows that the angular resolution for the laser systems can be increased up to one scalarlevel by this novel technology.
