激光引信大视场小型化发射光学系统设计

由于受系统体积限制,目前激光引信大视场探测方式无法满足小型化结构简单的需求。针对激光引信弧矢方向无漏探测、子午方向窄视场探测的技术要求,提出了一种小型化大视场激光引信发射光学系统的设计方法,采用由三个管芯线型阵列排布的隧道结半导体激光器作为发射光源,合理选择光学视场空间布局方式,设计了三象限扇形轮流发射方式激光引信发射光学系统,其特点在于体积小、视场大、结构合理,装调简单,单路发射光学系统体积为8 mm8.2 mm15 mm,单路弧矢方向探测视场达120。设计的发射光学系统能够满足弹径为70 mm的便携式防空导弹激光引信大视场目标探测要求,解决了周视激光引信小型化的需求问题。

Design of emission optical system for laser fuze with large FOV and miniaturization

Due to the limitations of system volume, the large field of view(FOV) detection method of laser fuze can not meet the requirements of system miniaturization. Aiming at the requirements of full detection in sagittal direction and narrow-FOV detection in meridian direction, a method of emission optical system with large FOV and miniaturization for laser fuze was proposed. The tunnel junction LD laser as a light source, a reasonable mode of FOV configuration was choiced, and an optical system with three-quadrant and sector-shaped emission was designed, which was characterized by small size, large FOV, reasonable structure, simple installation. The volume of single emission optical system was 8 mm8.2 mm15 mm, the single FOV in sagittal direction was more than 120. The large FOV detection requirements of portable laser fuze whose diameter was 70 mm for air defense missile was satisfied, and the problem of miniaturization for full FOV laser fuze was solved.
