Title: Light beam deflection system - uses deflection unit and mirror correcting scanning spot path
Inventor: BERGMANN UDO
IPC: G02B5/09
Filed: 1976-04-17
Abstract: The system has a mechanically movable deflector for straight line scanning of large format documents. A focussed light beam so falls on the movable deflection unit and the additional stationary mirror near the document to be scanned, that the focus track of the beam reflected from the deflection unit lies in a plane and is deflected by the additional mirror, so that a straight scanning track is produced on the document. The additional mirror shape depends on the unconnected track, and its generatrices are perpendicular to the scanning plane. Without using the auxiliary mirror as part of the optical system which is scanning the document, the focussing lens has such a long focal length, that the focus track approximates a circular arc. An opened cylindrical concave mirror, which is used as an auxiliary mirror and set in the path of the incident light beam, has a chord at least as long as the document to be scanned and lies parallel to the scanning line.
