The major effort on advanced photo facsimile transmission techniques was to experimentally demonstrate the feasibility of the ferrotron concept, and to explore possible means of matrix readout for the ferrotron. In the area of image transducing system analysis several methods of combining the exposure, readout and erasure functions of the image transducer into an integrated system are described. Special consideration is given to systems employing either the ferrotron, the polatron or the Daptron type of storage element. A promising concept for an image transducing element, the polatron, was evolved. Several matrix scanning techniques for the electronic readout of a stored image were investigated. A matrix using ferrotron elements overcomes the isolation limitations inherent in matrix arrangements.
