ABSTRACT:
An optical system providing a rotating scan disc including a circular array of concave reflectors on a planar surface thereof and imaging means adapted to coincide with the scanning sweep of the concave reflectors and separated from the concave reflectors by a distance equal to the focal length of the concave reflectors. A light source is provided to emit a light beam toward the circular array of concave reflectors to form an image redirected from the imaging means and the imaging means includes an objective mirror and a strip prism adapted to correct field curvature of the image. Additionally, means are provided to monitor the position of the light beam in both the scan and cross-scan directions and to reposition the light beam by movement of at least one optical component.
