摘　　要：为了提升导弹在复杂环境下的寻的制导能力,设计了一种红外与可见光双模式导引头光学系统。该方案中采用分光镜透射红外光反射可见光,使结构布局更加紧凑,实现红外与可见光共口径,同时配合红外材料选取,实现光学被动消热差设计。中红外模式视场角3°×2.3°,可见光模式视场角5°×4°,工作温度20℃条件下,双模式在截止频率处,MTF(Modulation Transfer Function)值均大于0.4。红外与可见光双模式光学系统适合应用于复杂环境的导弹制导,对温度有良好的适应性,具有较好的成像质量,满足系统的性能要求。A folding anti-infrared and visible-light double-pattern optical guidance system was designed to improve the guidance of a missile in complex environments.In this scheme,the system layout for infrared and visible light is produced by spectroscopic optical visible light reflection,realizing dual-mode infrared and visible light,and optical passive heat reduction is implemented.In the mid-infrared mode,the field of view of the infrared mode is 3°×2.3°,the angle of view of the visible light mode is 5°×4°,the working temperature is 20℃,and the dual mode MTF is greater than 0.4 in the cup-frequency.Infrared and visible-light dual-mode optical systems are suitable for missile guidance in complex environments,have good adaptability to temperature,and have good imaging quality and performance.
