<p>An optical apparatus monitors the entire panorama in low resolution and simultaneously monitors a selected portion of the panorama in high resolution. For the panoramic portion of the apparatus, a mirror (32) having a convex surface of resolution with a hole (35) therein is used. The higher resolution part of the apparatus uses a pointing mirror (50) positioned above this hole (35). The panoramic and higher resolution views are imaged through lenses or optical components (52, 36) onto a detector (42). The panoramic view is imaged onto the detector (42) as an annulus of light in which either higher or lower elevational angles of the panorama are imaged further away from the detector's center depending upon how the convex mirror (32) is configured. In this way, the resolution of that portion of panorama that is imaged further away from the detector's center is enhanced. The higher resolution view is imaged to the center of the annulus. Thus, both panoramic and higher resolution portions of the desired scene share the same detector array without interruption, interference, or overlap. The invention may be used for tracking projectiles and flying objects. <IMAGE></p> |
