    Abstract: 1. An ion laser comprising: A LINEAR DISCHARGE TUBE; SAID TUBE BEING FILLED WITH A QUANTITY OF GAS WHICH IS CAPABLE OF POPULATION INVERSION IN AN IONIZED CONDITION; MEANS FOR ESTABLISHING A SUBSTANTIALLY CONTINUOUS GAS DISCHARGE THROUGH SAID GAS; MEANS FOR MAINTAINING A SUFFICIENTLY HIGH CURRENT FLOW THROUGH SAID GAS TO IONIZE A SIGNIFICANT PROPORTION OF SAID GAS AND TO ESTABLISH A POPULATION INVERSION OF COMPONENT IONS; ENCLOSURES ATTACHED TO OPPOSITE ENDS OF SAID DISCHARGE TUBE; AND MEANS FOR EQUALIZING THE GAS PRESSURES ALONG SAID DISCHARGE TUBE COMPRISING AN AUXILIARY TUBE INTERCONNECTING SAID ENCLOSURES.

    Abstract: One surface of the target of a television camera device is scanned by a light beam, with light to be recorded being imaged on the opposite surface. The target comprises a substrate having a diode array on one side with a photoconductive layer being sandwiched between a transparent conductive film and the diode array. A voltage on the conductive film reverse biases the diodes. During one frame time, the diodes discharge as a function of light intensity imaged on the substrate. The scanning light beam recharges the diodes by increasing the localized conductivity of the photoconductive layer, and thus generates a video signal output.
