Abstract

An optical system incorporating a compact internal field of view switch configured to switch the field of view of the optical system between a narrow field of view and a wide field of view while maintaining a constant exit aperture size. In one example the optical system includes an active imaging sub-system optically coupled to the exit aperture, and the field of view switch is positioned between the exit aperture and the active imaging sub-system. In one example the field of view switch is configured as a pupil relay having non-unity magnification.
