This paper discusses the use of a vidicon storage tube in scan converter operations. It outlines the design considerations and pertinent characteristics of devices employing the storage vidicon in scan converter applications. It discusses optics, transfer characteristics and sensitivity considerations. It discusses the significant factors in choosing tube type, sweep circuits, and other associated electronics when assembling a special purpose instrument. It outlines modifications and operating techniques when utilizing an ordinary TV camera. Instruments designed and built by NOLC, both a general purpose laboratory instrument and an airborne unit, are described. The paper concludes by giving a number of example applications.
