A wide field of view imaging system ( 100 ). The novel system ( 100 ) includes a rotating mirror ( 18 ) having two reflective surfaces each surface, respectively, reflecting light from a scene to first and second sensors ( 10, 12 ) positioned to receive light from the mirror ( 18 ), wherein the first and second sensors ( 10, 12 ) each occupy a different portion of the volume surrounding the mirror ( 18 ). In the illustrative embodiment, the mirror ( 18 ) is a flat, double-sided mirror rotating at a constant velocity about an axis parallel with the surface of the mirror ( 18 ). The first and second sensors ( 10, 12 ) are all-reflective optical systems, with the first sensor ( 10 ) opposite the second sensor ( 12 ). In the preferred embodiment, the invention further includes third and fourth opposing sensors ( 14, 16 ) clocked 90° from the first and second sensors ( 10, 12 ). The first and second sensors ( 10, 12 ) cover an outer annulus of the field of view while the mirror ( 18 ) rotates a first 90°, and the third and fourth sensors ( 14, 16 ) cover an inner annulus while the mirror ( 18 ) rotates the next 90°.
