<p>An optical system including a scan disc (42) having concave reflectors (44) thereon is described. As an optical printer, positioned adjacent to the scan disc are a corrector lens (46), a strip mirror (48), and a primary mirror (50). Positioned adjacent to the image plane are a field mirror (52) and a pick-off mirror (50). Input light is directed onto the scan disc perpendicular to the plane of rotation. When one of the concave reflectors on the rotating scan disc is centered over one end of the strip mirror, the input light is brought to focus and is redirected to the primary mirror by the strip mirror. The primary mirror forms an image of the light spot after passing through the corrector lens. This image is intercepted by a field mirror which forms a final image of the spot. This image is picked out of the incident light beam by a thin pick-off mirror which redirects the light allowing image accessibility. With minor modification the optical system may also function as an optical scanner. <IMAGE></p> |
