摘　　要：介绍一种适用于线阵激光器光束扩束整形的光学系统设计方案。内容包括用途简述、研究思路、设计难点、解决方法及仿真测试结果。本光学系统主要用于激光主动探测系统的光源整形发射,运用到光学设计中的非球面、反射、折射、全反射等理论。可实现线阵激光器光束大视野角扩散,光束在视野角内扩散后能量分布按实际需求达到两边高、中间低,弥补使用中边缘视野比中间视野距离目标更远、探测性能降低的实际情况。A linear array laser beam for shaping the beam expander optical system design is Introduced, including description of uses, research considerations, difficulties in design process, suggested solutions and results of simulation. The optical system involving the application of certain theories in optical design such as theories of non-spherical, reflection, refraction and total reflection is mainly used for beam shaping of active detection system. It can achieve a large angle view linear array laser beam spread, and the energy is high on both sides and lower in the middle area. This can make up for the decreased detection capability resulting from the farther distance between the fringe areas of vision fields and the target than that between the central vision field and the target.
