Abstract
A seeker is disclosed including a Cassegrainian telescope, responsive to an optical signal having a signal path, for directing the optical signal toward an optical detector. The seeker also includes a first rotatable optical wedge, disposed in the signal path of the optical signal, for directing the optical signal from a first direction toward the Cassegrainian telescope. The seeker further includes a second rotatable optical wedge, disposed in the signal path of the optical signal, for directing said optical signal from a second direction to the first direction. With such an arrangement, a seeker is provided which is capable of surviving a high 'G' application and providing a wide field of view. The seeker provides two angular degrees of freedom in polar coordinates for the optical signal just as a two axis gimbal provides two angular degrees of freedom in Cartesian coordinates.
