    Abstract: An off-axis reflective transmit telescope for a DIRCM system is mounted on the gimbal along a transmit-axis offset laterally from the optical axis of the receive telescope but nominally aligned with the line-of-sight of the receive telescope to transmit a laser beam. The telescope comprises an optical port optically coupled to a laser to receive and direct the laser beam away from the dome and a reflective optical assembly that reflects the laser beam through the dome. The reflective optical assembly comprises an off-axis mirror segment and a second optical element that together precompensate the laser beam for dome aberrations induced by the lateral offset of the transmit telescope's transmit axis from the optical axis. The off-axis mirror segment comprises a segment of a parent mirror having an aspheric curvature (e.g. parabolic, elliptical or higher-order asphere) about an axis of symmetry. The segment is offset so that it is not centered on the axis of symmetry of the parent mirror. The use of the off-axis mirror segment allows the optical port and any folding mirror to be positioned so that they do not obscure the reflected laser beam. The second optical element may be a segment of a dome corrector parent lens, a prism or a refractive lens formed on the front surface of the off-axis mirror segment.

    Abstract: A control mechanism pins an optical fiber assembly on and off gimbal and between gimbals to route the assembly from an off-gimbal optical source across the gimbal axis/axes to an on-gimbal optical element so that the fiber assembly moves with the rotation of the gimbals. To accommodate a relatively large range of motion, the control mechanism is suitably configured to route the fiber assembly in a "U-shaped" loop with one end pinned off-gimbal in a stationary guide track and the other end pinned on-gimbal point in a rotating guide track so that the loose fiber assembly is constrained in the concentric tracks on and off gimbal. As the gimbal rotates, the loop seats onto one guiding track and peels off of the other guiding track while always maintaining its U-shape. To accommodate a relatively small range of motion in other gimbal configurations, the control mechanism is suitably configured to pin one end of the fiber assembly off-gimbal and pass the fiber assembly directly over the gimbal where it is pinned on the other side of the gimbal. In a multi-gimbal pointer, the fiber assembly preferably exhibits different mechanical stresses as it crosses the different gimbals.
