摘　　要：设计了一种折叠式光学系统来缩短微光夜视仪轴向尺寸,提升头戴式微光夜视仪佩戴舒适性。首先给出总体设计,包括折反式物镜和长工作距离、双通道目镜系统设计,之后通过理论计算获得物镜和目镜的指标参数,最后选用符合要求的初始结构,采用软件对折叠式光学系统进行优化设计。采用折叠式光学系统的微光夜视仪,与传统直视型夜视仪相比轴向长度由110 mm减少到70 mm,更接近佩戴者头部,可以有效提升佩戴舒适度。A folding optical system which was aimed to shorten the axial length of the low-light-level night vision goggles was designed to improve the wearing comfort.Firstly,the overall design was given,which included the design of a foldable objective lens,a long working range,and dual channel eyepiece system.Next,the parameters of the objective lens and eyepieces were obtained through the theoretical calculation.Finally,an initial structure that met the requirements was selected,and the folding optical system was optimized by using the software.Compared to the traditional direct-view night vision goggles,the axial length of the night vision goggles was reduced from 110 mm to 70 mm by using folding optical system,which was closer to wearer’s head and could effectively improve wearing comfort.
