    摘要: A missile defense system (20) for aircraft includes a laser (12) for generating infrared light, a turret (22) that can direct the light toward a missile to blind its infrared sensors, and an optical fiber (14) for delivering the light to the turret (22). The system (20) includes a coupling device (10) for directing the light from the laser (12) into the optical fiber (14). The coupling device (10) includes a light-guiding assembly (24) with one or more lenses or other optical devices to direct the light into the optical fiber (14). The coupling device (10) also isolates the input end of the optical fiber (14) from the environment with an optically-transparent window (26) and provides a way to use a different light-guiding assembly (24) with different lasers (12). The window (26) isolates the end of the fiber (14) from any contaminants in the environment to keep the optical fiber (14) relatively clean, and thereby provide a suitable surface for the light to enter the fiber (14).
