摘要
基于CMOS器件的低照度夜视装备隐蔽性好,成本较红外热像装备低,是拓展人眼低照度条件下视觉感知的重要手段,在军事和民用领域都有广泛应用。为满足夜间低照度天候条件下装备维修保障需求,设计了一款大视场低照度夜视头戴目镜光学系统。通过选择合适的光学玻璃材料,在可见/近红外波段均有很好的光谱响应。设计完成的大相对孔径目镜视场角为74.46°,焦距为46 mm,F数为1.2,畸变小于-7.14%,系统总长小于80 mm,且镜头总质量小于100 g。该目镜在486 nm~950 nm光谱范围内能够满足夜间无照明条件下的维修、训练和场景观察,为低照度夜视头戴系统光学模组研制提供了新的技术手段。
Low-illumination night vision equipment based on complementary metal-oxide-semiconductor(CMOS)devices has good concealment and lower cost than infrared thermal imaging equipment.It is an important means to expand human visual perception under low illumination conditions and widely used in military and civil fields.In order to meet the requirements of equipment maintenance and support under low illumination condition at night,an optical system of night vision goggle with large field of view and low illumination was designed.By selecting the appropriate optical glass material,it had a good spectral response in both visible and near infrared bands.The designed eyepiece with large relative aperture had a field of view angle of 74.46°,focal length of 46 mm,F number of 1.2,distortion less than−7.14%,total length of the system less than 80 mm and lens weight less than 100 g.Under the spectral range of 486 nm~950 nm,the eyepiece can meet the maintenance,training and scene observation without lighting at night,which provides a new technical means for the development of optical module of low-illumination night vision head-mounted system.
