ABSTRACT:
A scanning optical system for incrementally generating a composite image of a strip-scanned object. A light beam is swept by a first rotating mirror across the object to scan-illuminate same. Imaging light from the object is then projected to an intermediate image station across which it is swept by a second rotating mirror. A stationary aperture at the intermediate image station transmits or reflects, at any instant, only a desired incremental image of the scanned object. This desired incremental image is in turn relayed to a final image plane by reflection from a third rotating mirror so as to synchronously lay down on the image plane a composite of the instantaneous increments.
