Abstract : Development of the photoconductor, ferroelectric and electrodes was continued. Adhesion and sensitivity of the photoconductor were improved. Polycrystalline ferroelectric layers showed poor square loop properties. Development of new fabrication techniques to overcome the deficiencies of both the photoconductor and the ferroelectric has continued. An experimental setup was built to measure the square loop properties of the ferroelectric at the operating frequency of the Ferrotron image plate. Several image plates of various sizes were constructed. The compatibility of the photoconductor with the ferroelectric and the transparent electrode was not resolved completely and requires further investigation. Design of the Ferrotron readout device consisting of a light spot scanner and a printer was completed. Experiments with the optical portion of the readout device showed that the scanning beam is as small as .0008 inch in diameter. The performance of the Ferrotron feasibility model agrees with requirements of an advanced facsimile image transducer. (Author)
