    • Abstract
  • 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.
