在激光跟踪导弹、卫星等飞行物时,需要一种对返回的激光束进厅分光、延时的器件。本研究采用屋脊棱镜。将光束分为四路,然后利用光纤进行延时;采用自聚焦透镜使激光束与光纤的耦合效率≥70％,采用光纤熔融拉锥元件与接收管耦合,使四路输出此的不均匀性≤±5％。 In the laser tracking missiles, satellites and other flying objects, the need for a return to the laser beam into the hall spectroscopy, delay device. The study uses roof prisms. The beam is divided into four, and then the use of optical fiber delay; the use of self-focusing lens so that the coupling efficiency of the laser beam and optical fiber ≥ 70%, the use of fiber-optic fused taper components and receiver tube coupling, the four output of this non-uniformity ≤ ± 5%.
