Abstract

An anamorphic condensor can be utilized as a line scanner when delivering information from a transparent slide or other similar media to a Charge Coupled Device (CCD) array or photoreceptor. More specifically, an anamorphic condensor provide linear illumination for a projection system which is used to deliver information from a transparent slide or other similar media to a CCD array, to be converted, one line at a time, into digital information which can be either stored or used as an input to a digital copier, or directly to a photoreceptor in a xerographic machine to provide a hard copy record thereof. By utilizing the proposed anamorphic condensor, the only motion required to convert the slide to either digital information or an image on a xerographic photoreceptor is the motion for moving the slide through the linear illumination of the film gate.

ANAMORPHIC CONDENSER FOR LINE SCANNER (Cont'd)

An anamorphic condensor can be utilized as a line scanner when delivering information from a transparent slide or other similar media to a Charge Coupled Device (CCD) array or photoreceptor. More specifically, an anamorphic condensor provide linear illumination for a projection system which is used to deliver information from a transparent slide or other similar media to a CCD array, to be converted, one line at a time, into digital information which can be either stored or used as an input to a digital copier, or directly to a photoreceptor in a xerographic machine to provide a hard copy record thereof. By utilizing the proposed anamorphic condensor, the only motion required to convert the slide to either digital information or an image on a xerographic photoreceptor is the motion for moving the slide through the linear illumination of the film gate.

Figure 1 illustrates a top view of the proposed anamorphic condensor for the line scanner. In Figure 1, the first cylinder lens element 1 has no optical power and the second cylinder lens element 2 concentrates the light from the source into the aperture of the projection lens 3. More specifically, the second lens element focuses a two dimensi...
