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).

摘要： An optical transceiver is provided with a light pipe that intercepts, offsets and redirects a portion of the collimated transmit beam to create a virtual object in the receiver field-of-view to perform the BIT. The light pipe comprises an input face and first reflective surface in the transmitter FOV to intercept a portion of the beam along a first axis and re-direct the beam, a second reflective surface and output face in the receiver FOV that re-directs the portion of the beam along a second axis towards the receiver to create the virtual object in the receiver FOV and an optical channel that guides the redirected portion of the beam from the first reflective surface to the second reflective surface to offset the second axis from the first axis. The same detector used during normal operation of the transceiver is used to perform the BIT, which may include a simple “on/off” test or a radiometry test. The light pipe may be designed with an acceptance FOV that preserves collimation, which facilitates a measurement of alignment error between the transmit beam and receiver.
