ABSTRACT:
Holographic lenses are formed on a substantially transparent scanning disc wherein a line focus is the object for each hologram. Such hologram is then used to reconstruct the line focus at the location of the record to be scanned, thereby alleviating tolerance requirements in regard to the positioning or flatness of the scanned record.
