Claims

1. MEANS FOR UTILIZATION IN AN IMAGE AMPLIFYING APPARATUS COMPRISING:

(A) A LIGHT CONDUCTING CORE HAVING A PREDETERMINED INDEX OF REFRACTION, A LONGITUDINAL DIMENSION EXCEEDING ITS CROSS SECTIONAL DIMENSION, A FIRST TRANSVERSE END, A SECOND TRANSVERSE END AND AN OUTER SURFACE EXTENDING FROM SAID FIRST END TO SAID SECOND END ALONG SAID LONGITUDINAL DIMENSION;

(B) A LIGHT CONDUCTING JACKET HAVING AN INDEX OF REFRACTION LESS THAN SAID PREDETERMINED INDEX DISPOSED UPON A FIRST PORTION OF SAID OUTER SURFACE OF THE CORE EXTENDING A PREDETERMINED DISTANCE FROM SAID FIRST END;

(C) A FIRST LAYER OF PHOTOCONDUCTOR MATERIAL DISPOSED UPON A SECOND PORTION OF SAID OUTER SURFACE OF THE CORE SO AS TO PROVIDE A TUBULAR PHOTOCONDUCTOR HAVING A PREDETERMINED LONGITUDINAL DIMENSION EXTENDING FROM SAID JACKET ALONG SAID SECOND PORTION TO SAID SECOND END;

(D) A SECOND LAYER OF PHOTOCONDUCTOR MATERIAL DISPOSED UPON SAID SECOND END AND CONNECTED ELECTRICALLY WITH SAID FIRST LAYER OF PHOTOCONDUCTOR MATERIAL;

(E) ELECTRICALLY CONDUCTING MATERIAL DISPOSED UPON SAID JACKET SO AS TO PROVIDE A TUBULAR CONDUCTOR BETWEEN SAID FIRST END AND SAID TUBULAR PHOTOCONDUCTOR AND CONNECTED ELECTRICALLY WITH SAID TUBULAR PHOTOCONDUCTOR ADJACENT SAID JACKET;

(F) SAID TUBULAR CONDUCTOR BEING ADAPTED TO EXTEND A VOLTAGE TO SAID TUBULAR PHOTOCONDUCTOR;

AND (G) SAID JACKET BEING ADAPTED TO CONTROL THE REFLECTION OF LIGHT THROUGH SAID CORE TO SAID FIRST LAYER AND TO SAID SECOND LAYER AND PREVENT THE ABSORBING OF SAID LIGHT BY SAID TUBULAR CONDUCTOR.
