<p>An infrared seeker for use in a spinning projectile (15) includes a Cassegranian telescope (11, 13) having a tapered optical wedge (21) overlying the entrance aperture, such wedge (21) being rotatably mounted to allow scanning and tracking, and a jettisonable streamlined cover (35) overlying the optical wedge (21) to reduce drag so long as such cover is in place. The telescope (11, 13) overlies a cryogenically cooled infrared detector assembly (19), and a servo motor having a rotor (29) connected through a cylindrical member (25) to the wedge (21) is provided for rotating the wedge (21).</p> |
