摘要： A coude gimbal structure (30) includes a two-axis gimbal system (36) having an outer gimbal (38) pivotable about a first rotational axis (40), and an inner gimbal (42) supported on the outer gimbal (38) and pivotable about a second rotational axis (44) which intersects the first rotational axis (40) at an intersection point (46). A reflective coude optical system has a positive-optical-power primary mirror (58) mounted to the inner gimbal. The primary mirror is directed along a third axis passing through the intersection point and lying perpendicular to both the first and second rotational axes. In one aspect of the invention a coude path length of the reflective coude optical system is about half of the aperture diameter of the primary mirror. In another aspect the structure has an intersection flat fold mirror at the intersection point.
