Abstract
An optical system comprises a pair of Risley prisms positioned along an optical axis to receive a light beam from a field of view, wherein at least one of the Risley prisms is rotatable, transverse to the optical axis, with respect to the other of the Risley prisms. At least one lens is positioned along the optical axis to receive the light beam from the pair of Risley prisms, with the at least one lens configured to focus the light beam. An optical detector array is positioned along the optical axis at an image plane, wherein the optical detector array receives the focused light beam on the image plane from the at least one lens. The optical system can be implemented as a light beam steering mechanism in a star tracker or celestial aided inertial navigation unit.
