Abstract
An optical seeker comprises a rotor (16) mounted on a bearing sleeve (42) to pivot about a pivot point (26) and to rotate about an axis of rotation (28). The rotor (16) carries an imaging system having a concave mirror (50) and a secondary mirror (52). The optical axis of concave mirror (50) and secondary mirror (52) form an angle with the axis of rotation (28). A sunshade (54) is connected to the rotor (16). The bearing sleeve (42) carries an optical element (56). An axle portion (58) is provided on the element (56), on which axle portion the secondary mirror (52) is mounted. The secondary mirror (52) is connected to the sunshade (54) through a stepping-up planetary gear having internal toothing (72), planet wheel (76) and external toothing (78). The planet wheel (76) is mounted on a carrier (74) connected with the axle portion (58).
