ABSTRACT:
A long-length industry camera image sensor (LICIS) is proposed for, expressed in X-Y-Z coordinates, converting a pixel line image (PLI) of length LPLalong X-direction into a line image signal (LIS). The LICIS includes a full-width linear image sensor (FLIS) of length LISalong X-direction and displaced from the PLI along Z-direction by an imaging distance DIMGfor converting an incident line image (ILI) impinging upon its FLIS top surface into the LIS. Where LISis about equal to LPL. The LICIS also has a full-width linear rod lens (FLRL) of length LRLalong X-direction and displaced from the PLI in Z-direction by a working distance DWKG. Where LRLis about equal to LPLand DWKGis selected such that the PLI gets focused by the FLRL into the ILI at the FLIS top surface with an imaging magnification factor of about 1:1.
