Abstract
Abstract A silicon diode array scan converter storage tube is disclosed which, after a diode array target has been electrically prepared, has information written on the diode array target in a writing mode, the information is transferred to an oxide coating of the target to store same, and the target is subjected to a scanning mode while being illuminated, thereby producing an electrical readout signal corresponding to the stored information thereon.
